We want to integrate "AFE (Ajax File Explorer) into our Drupal application. Our users are authenticated in Drupal and it is not possible for us to ask a second time there login/pwd while opening AFE.
We received a first answer from ITHIT:
Here is how to set login and password:
ajaxFileBrowser.GetSession().SetCredentials('User1', 'pwd');
Please note that this API sets password in XHR. Setting login and
password in XHR does not provide any feedback on weather the login was
successful. That is why in general I would suggest to rely on web
browser login dialog which is displayed automatically instead of
calling SetCredentials.
However it is not clear if it is a real and robust SSO solution. We discovered that Drupal has an webdav SSO module (https://github.com/Awnage/webdavsso), we will also investigate that part. But any comment/help welcomed.
To my understanding there is no way to totally get rid of login dialog when using Basic, Digest, NTLM or Kerberos authentication with Microsoft Office.
Microsoft Office applications always ask for the authentication when used with Basic or Digest authentication. This is a Microsoft Office and Microsoft Mini-redirector limitation and there are no workaround in case your server is using Basic or Digest.
However, if you check "Remember my password" check-box it will still display the login dialog, but the user name and password will be already filled-in, so you just click "OK".
Here are some options to consider if you need to totally suppress login dialog with Microsoft Office:
Use NTLM or Kerberos authentication. In case of NTLM or Kerberos MS
Office asks for credentials only 1 time during first document access.
Implement Office Forms Based Authentication Protocol (MS-OFBA).
Implement Url-authentiation. Your urls will look like:
http://webdavserver.com/[SessionID1234567890]/path/file.docx.
In case of Url-authentiation make sure you do not include the session ID in query string, Microsoft Office will truncate it. You will have to put session ID somewhere in the path, as in the above example, which is not very convenient, when you need to mount a WebDAV folder in you file system, but still works in most cases.

I solved that problem in the same manner.

We have a code that logins to Sharepoint Online using :
https://login.microsoftonline.com/extSTS.srf or https://login.microsoftonline.com/RST2.srf, but recently we starting to get authentication failed saying that "Incorrect Username or Password" and after some retries it returns:
"0x80048823 message : AADSTS70002: Error validating credentials. AADSTS50053: You've tried to sign in too many times with an incorrect user ID or password."
While using same username and password to login in the browser works fine, and neither password or username were changed, also code didn't changed. As same code works fine for another Sharepoint tenants. Seems that something changed in the Microsoft login servers, where it's started to not accept user credentials, while web browser login works fine.
Please advise.
Thanks
Microsoft Rep has helped me get this far.
They had us create a "Cloud Only" user. This user was setup as "#" so if your name is bill and your corporate sharepoint site is name is FakeCompany.sharepoint.com then you would have the person as "bill#FakeCompany.onmicrosoft.com"
This user was able to login to https://login.microsoftonline.com/extSTS.srf by just passing username and password.
Our on prem AD users are still having issues, i mentioned this and got the following response.
There is no issue with sync as you are able to login to portal using the same account and password.
The solution you need is documented in https://learn.microsoft.com/en-gb/azure/active-directory/manage-apps/configure-authentication-for-federated-users-portal#enable-direct-authentication-for-legacy-applications
You need to create a home realm discovery (HRD) policy where "AllowCloudPasswordValidation":true.
We have not yet implemented the last solution but the creating of a cloud account may help some of you.
So I think I understand what they are trying to say. There are 2 paths that you are able to authenticate with according to the node-sp-auth example.
"Managed" and "Federated"
"Managed" was the easier version and allowed for you to be able to just provide username and credentials in a soap assertion to login.
Federated is a lot more complicated. You need to first perform a post to Microsoft to validate the user hitting your adfs server. https://adfs.XXXXXXX.com/adfs/services/trust/13/usernamemixed
Then you take the saml:Assertion from that response and put it into the "Token" section of the call you make to https://login.microsoftonline.com/extSTS.srf utilizing the templates from the node-sp-auth.
I have C# code that performs all these steps but I am getting an error
AADSTS70002: Error validating credentials. AADSTS50008: SAML token is invalid. AADSTS50006: Invalid signature. Signature verification failed.
Even though the signature is being generated by Microsoft in their SAML.
node-sp-auth code refrence is OnlineUserCredential.ts file.
If someone can figure out the last mile I can post a comprehensive C# solution.
So for a while I've been relying on the PLAIN support for logging into Google's IMAP server in my email client. Recently they started blocking that and return an error (despite listing it as a supported authentication method).
For instance take this example:
Connected to 'imap.gmail.com:993' using SSL
A0001 CAPABILITY
* OK Gimap ready for requests from ##.##.##.## cd6mb38777249ieb
* CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN X-GM-EXT-1 XYZZY SASL-IR AUTH=XOAUTH2 AUTH=PLAIN AUTH=PLAIN-CLIENTTOKEN AUTH=XOAUTH
A0001 OK Thats all she wrote! cd6mb38777249ieb
A0002 AUTHENTICATE PLAIN

ScribeImap_Thread.cpp:647 - Connect to imap.gmail.com:993 failed.
I've tried opening the "https://accounts.google.com/ContinueSignIn..." URL in my browser:
And I get redirected to https://myaccount.google.com/ but the next login attempt fails as well. So it doesn't seem to change the authentication at all.
Is the PLAIN authentication just blocked completely or am I doing it wrong?
Alternatively is there a authentication method that works and DOESN'T need a browser component to log in? (XOAUTH2 seems to need a web login as well)
It's pretty official:
http://googledevelopers.blogspot.com.au/2015/04/a-final-farewell-to-clientlogin-oauth.html
They have shut off PLAIN login completely and it's not coming back.
So there are two options:
Turn on "less secure apps".
Implement OAUTH2.
I've decided to implement OAUTH2 support (which isn't too far off working actually). Initially I thought I would need an embedded browser component in my app, but it turns out that I can launch the system browser and the user can copy the token across in a some what manual process.
Interestingly for those working on OAUTH2 support in their software, Google have setup a playground to see the whole process in practice:
https://developers.google.com/oauthplayground/
I see that this is an old post, but after fighting with Outlook for over a year to get my mail, I FINALLY got it working again.
The first thing I had to do was log into my my Gmail account and turn off the button labeled "Less secure apps" as Outlook is in that category.
Go to the "Less secure apps" section in My Account.
Next to "Access for less secure apps," selectTurn on. (Note to Google Apps users: This setting is hidden if your administrator has locked less secure app account access.)
And if you have 2-step verification on (as I did), it will still make Outlook fail. So the next thing you have to do is create an app password which will generate a password for you, and you use that in Outlook for it to sync correctly.
Visit your App password page. You may be asked to sign in to your Google Account.
At the bottom, click Select app and choose the app you’re using.
Click Select device and choose the device you’re using.
Since Outlook will not be listed, select Other and type in Outlook for future reference.
Select Generate.
Follow the instructions to enter the App password (the 16 character code in the yellow bar) on your device.
Select Done.
Copy the password that was generated.
Open Outlook and paste the password in the Password section. DO NOT use your regular password.
Your mail will sync without anymore issues. (Hopefully)
Once you are finished, you won’t see that App password code again. However, you will see a list of apps and devices you’ve created App passwords for.
I hope this helps everyone who is having an issue. And I hope these directions are easy to follow! Good luck everyone! :-)
I would like to understand something please.
I have an application based on oAuth2 with Google Accounts.
So, teh first time I connect to this website, I am redirected to the authentication page on Google domain. So I type my email and password and I dont check "trusted computer" (or "remember me", I dont remember the exact term).
The thing is if I reboot my computer or even delete my cookie (but not my history (tested with Chrome on Android phone), I am not prompted again for the authentication and I have directly access to the application.
I would like to understand why ?
If somebody can explain it to me that should be great !
Thank you
You can actually force re-authentication in the Google OAuth api by passing &max_auth_age=0 to the auth URL.
Source:
Use the PAPE extension for further control of user authentication (optional)
Use the max_auth_age parameter in the PAPE extension to ensure that the login session of the user at Google is recent. You may also specify max_auth_age=0 to force a password reprompt.
https://developers.google.com/accounts/docs/OpenID
It's a bit confusing because they talk about OpenID, but I'm doing this successfully with Google's provided OAuth2 libs.
The Google OAuth 2 API really doesn't give you a way to force re-authentication. Lots of people have asked for this capability though, and maybe we should provide it.
It's hard to say, since it depends on what the flow was that as being executed.
Generally (with oauth) you weren't being prompted for authentication. You were being prompted for authorisation. Once you've authorised, you won't be prompted again, provided of course that the browser/google have some sort of session in existence which identifies the user.
When you say "delete my cookie", which cookie?
Yo can try going to this page https://accounts.google.com/b/0/IssuedAuthSubTokens?hl=en_GB and revoke the permission. That should then cause a repeat prompt.
I have an asp.net web application in an internal windows domain which calls a wcf-service. In the wcf-service I use the SecurityContext.Identity.Name, so it needs impersonation.
Our task is that the web application can be accessed from anywhere.
The first step was that the administrators published the web application throught ISA server 2006. The main problem with this solutions is that the browser doesn't save the user's loginname and password in the ISA authentication form. In addition the users want to access the webapp from Nokia Mobile with Opera Mini.
What can I do in a simple way that the browser saves the loginname/password in order to the user can use the application without reentering the login data in every 30/60 minutes?????
Any best practise?
The standard is to store the username/password in a cookie and have the login page pull the login info from the cookie to auto-login. You can have this cookie expire in a month if you want to.
Here are some examples using different languages to add a "remember me" type functionality to save username and password in a cookie.

Response to creator's comments:
In order to modify the ISA login page, look at this article. You should be able to add the code top handle cookies by editing the login page file located in the directory C:\Program Files\Microsoft ISA Server\CookieAuthTemplates\ISA\HTML (assuming you installed ISA to that location).
I do not think there is an out of the box configuration that allows you to set this up, but I did see some configuration for setting trust level (#18 from the article) that you might want to play with.
We have our own web server hosting our website that is open to the public outside of our network.
I have a request to make our "Internal Postings" link on our Careers page to authenticate the user against our network's Active Directory list.
I currently have it setup so the link hits a page inside the directory structure of the website, and this page's folder is set to "Integrated Windows Authentication". Anonymous access is turned off for this page. If the user is authenticated (ie: logged into our network or supplies proper credentials) it passes them on to an external careers website which hosts our job postings. If they fail to authenticate, it displays a custom 401 error page.
This works fine, but there is a problem with it. Using IE, people cannot just enter their username. They (of course) are required to enter the domain name as well. Unfortunately the default 'domain' is set to the URL of our website (www.xyz.com/username). I would like it to automatically choose the name of our internal domain (aaa/username) but am unsure of how to do this.
Another option would be to use LDAP and a little ASP scripting to authenticate the user. I have this code already, but am unsure of the security consequences of doing so. Basically, the page will be setup for anonymous authentication, and if the user isn't logged into our network, they will be prompted for a username/password using standard textboxes. This is then passed to an ASP script that does an LDAP lookup against our Active Directory. Is there any security issues with this method?
Which method would you choose to do?
Thanks.
EDIT: It seems I cannot authenticate to ActiveD via LDAP using a username/password combo. So forget about that option.
My question now is, how can I change the default 'domain' that IWA uses? Is that at all possible? IE seems to default to 'www.xyz.com\username' (my website) rather than 'aaa\username' (my domain name). Of course, www.xyz.com\username fails because that is not where our ActiveD resides... Is this possible? I want to make it as simple as possible for our employees.
You cannot authenticate an user with a script that looks up the user in LDAP. You need to know that the user is who it claims it is, and the only way to do that is to let NTLM/Kerberos authenticate the user (ie. establish proof that the user knows a secret stored in the AD, the password).
The URL of the web site to the set of sites considered be in the local intranet zone for IE browsers running on the internal network. By default sites consider to local intranet will be sent the current logged on users credentials when challanged with NTLM/Kerberos. Hence your internal users shouldn't even see a network logon box.
I hate to dredge up an old thread, but the answers are a bit misleading, if I understand the question. The thread Remus refers to is about authenticating via LDAP with a username only. As he points out, that isn't possible. But it looks like what Kolten has in mind is authenticating via LDAP with a username and password both. That's a standard practice called binding.
