I am using Streamset Data Collector version 3.19.1, currently am trying to integrate Streamset with LDAP server for authentication, I am successful with the integration however we are facing difficulties in configuring the roles and groups like the way it is in File based.
i.e in file based you have three things to configure a)user b)role c) group
<user name>: MD5:<md5-text>, user, <role> [, <additional role>, <additional role>...] [, group:<group>, group:<additional group>...]
if you look at above syntax, there is user name which can be user defined, then there is user which is fixed value, then we have role it can be one of (Admin,Manager,Creator and guest) and last we have group which us again user defined this can be used for Multitenancy.
however now comparing to LDAP configuration provided by streamset we have only following attributes to configure.
<ldap group>:<SDC role>,<additional SDC role>,<additional SDC role>);<ldap group>:<SDC role>,<additional SDC role>...
from above syntax we can see can be configured which is user defined and SDC role which can be one of the following(Admin,Manager,Creator and guest) with this the configuration will look like
DEV:creator;OPS:manager;
how can I configure LDAP rule mapping for group and role, currently i can only map for role in LDAP, requesting anyone to help here, i tried all my best to resolve unfortunately couldnt find any solution.
You can use the same configuration for groups as well. Following from my environment.
http.authentication.ldap.role.mapping=operators:admin;
To get the groups ldap-login-conf needs to be configured like following:-
roleBaseDn="OU=operations,OU=test_groups,OU=groups,OU=sdc,DC=example,DC=COM"
roleNameAttribute="cn"
roleMemberAttribute="member"
roleObjectClass="group"
roleFilter="member={dn}";

I am trying to setup User Federation from a LDAP server to Keycloak. I managed to import all the users and groups respectively from LDAP server, however, the user-group (group tab in Users section) doesn’t show the actual mapped groups, although I can see those users presenting in the groups listed in Members tab in Groups section…
I went through all article in Keycloak forum/Jira ticket/Mail list and I did find a ticket describing the exact issue that I am experiencing now (https://lists.jboss.org/pipermail/keycloak-user/2018-February/013076.html) and Marek has also replied to that as well, however, I still couldn't figure out what configuration I set incorrectly just by the information provided in the post.
Could anyone please help me out? Thanks ahead!

Looks like the issue was in LDAP server. The problem only exists when I import the users from FreeIPA DB. However, when I try to federate to an AD server, the user-group information just comes along with the users without any additional modification!
Below is the configuration I have used in the successful case. Hopefully it will help others who encounter with a similar issue. Thanks everyone for the attention.
[User Federation Provider Settings]
Enabled: ON (Default)
Console Display Name :

The rest of setting leave it blank.
You need to configure a group-ldap-mapper as well

Mapped Group Attributes:
Drop non-existing groups during sync: ON
I connected our active directory to keycloak (4.0.0.Beta1) and imported the users - this works fine.
But the username should be filled from sAMAccountName. So i changed the Username LDAP attribute to that.
But after clicking Synchronize all users i am getting this error in the console window:

I tried some mappers (especially username) but with no luck. It seems that there are only a few attributes read from the ldap server (see attributes from LDAP:... in the output).
Namely: whenChanged, whenCreated, mail, givenName, sn, userAccountControl, pwdLastSet.
How can i get the sAMAcountName attribute as username?
I have just tested it in 4.1.0.Final and there it works when you change the Username LDAP attribute to sAMAccountName and additionally the
LDAP Attribute in the username mapper also to sAMAccountName.
I tried some mappers (especially username) but with no luck.
Your question suggest, that you already tried doing something in the username mappers. So you were definetly on the right track. Either there was a bug in your version, or the two fields didn't match correctly.
For me, it worked. Please find the below process:
1) In User Federation -> LDAP Provider -> There is a setting called "UserName LDAP Attribute". (as shown here ldap provider settings)
2) Select Mappers tab and edit "username" mapper and change to following settings: username mapper settings
Problem:
I need to limit access to a WCF service using only Windows account settings. I have a WCF service with security binding element 'clientCredentialType' set to 'Windows'. Can't change this setting. If I understand correctly, anyone with an authentic windows account is authorized as long as they meet the authorization rules set by the file (EXE) that is hosting that WCF service. So I went into Powershell and queried the settings for that service:
Get-Acl MYSERVICE.exe | Format-List
says:
Path : Microsoft.PowerShell.Core\FileSystem::C:\Program Files (x86)\Blah\Server\MYSERVICE.exe
Owner : BUILTIN\Administrators
Group : MYDOMAIN\Domain Users
Access : NT AUTHORITY\SYSTEM Allow FullControl
BUILTIN\Administrators Allow FullControl
BUILTIN\Users Allow ReadAndExecute, Synchronize
APPLICATION PACKAGE AUTHORITY\ALL APPLICATION PACKAGES Allow ReadAndExecute, Synchronize
Audit :
Sddl : O:BAG:DUD:AI(A;ID;FA;;;SY)(A;ID;FA;;;BA)(A;ID;0x1200a9;;;BU)(A;ID;0x1200a9;;;AC)
Every user in my domain seems to have access.
Question, how do I change 'MYDOMAIN\Domain Users' to a different group in my domain so that every domain user (in that group) does not have access?
I have been able to change the list of accounts and their permissions under 'Access' like this:
$perm = "My Other Domain Group","FullControl","Allow"
$rule=New-Object System.Security.AccessControl.FileSystemAccessRule $perm
$myservice_acl.SetAccessRule($rule)
And can presumably explicitly deny or grant access but how do I change the group it inherits from? Or is this the correct approach?
The Windows Security Descriptor(SD) is broken up into four primary parts:
Owner
Group (or Primary Group)
Discretionary Access Control List (DACL)
System Access Control List (SACL)
The Primary Group part of the SD is ignored and has been ignored since Windows 2000 and was preserved for backwards compatability with POSIX operating systems. https://technet.microsoft.com/en-us/library/cc961983.aspx
For your case, the only two fields to concern yourself with are the Owner and the DACL.
The Owner has implicit Full Control over the Securable Object.
The DACL is a list of Access Control Entries (ACEs) which defines Security Identifiers (SIDs or trustees) that have a level of access rights defined.
In other words, if you are concerned about the SD on your service binary, check the owner and all members of the DACL but not the Primary Group.

https://msdn.microsoft.com/en-us/library/windows/desktop/aa379563(v=vs.85).aspx
EDIT: For the sake of completeness, the SACL is a list of ACEs (trustees and access rights) but instead of governing control, it controls who is audited and for what type of behavior.
Group: The security group of the owner.
only users in following groups are able to reach folder\object:
NT AUTHORITY\SYSTEM Allow FullControl,
BUILTIN\Administrators Allow FullControl,
BUILTIN\Users Allow ReadAndExecute, Synchronize,
you should check only access property to add/remove/query who has access to the folder\file
Domain users have access via the local group BUILTIN\Users (joining a computer to a domain automatically adds the group DOMAIN\Domain Users to the group BUILTIN\Users on the joining host). The group property of the security identifier has nothing to do with the access.
If you want to prevent access by domain users in general and allow just a particular domain group you'd remove the DOMAIN\Domain Users ACE and add an ACE for the desired group:
$ace = $myservice_acl.Access |
Where-Object { $_.IdentityReference -eq 'DOMAIN\Domain Users' }
$myservice_acl.RemoveAccessRule($ace)
$ace = New-Object Security.AccessControl.FileSystemAccessRule ('DOMAIN\Other Group', 'FullControl', 'Allow')
$myservice_acl.AddAccessRule($ace)
Set-Acl -AclObject $myservice_acl -Path ...
If you just want to deny access to a particular user you could also create a deny ACE for that user. However, mixing permissions like that tends to become pretty messy pretty fast, so I wouldn't recommend going this route.
I am trying to use ldap for a flask application .
The app.config['LDAP_PROVIDER_URL'] = 'ldaps://appauth.corp.domain.com:636'
(I have replaced the domain for the original name here)
In another script in need the following ldap details
conn.simple_bind_s(
'cn=%s,ou=Users,dc=corp,dc=domain,dc=com' % username,
password
)
How do I find the OU,or can i ignore OU and drop it from above. Please let me know if other parameters are correct. I don't know LDAP
The general idea is that you bind as an application account with search privileges to locate the user account, e.g. by his email address, displayName, etc., and then use that DN to rebind using the password he supplied.
I am currently working on a project that uses OpenAM 12.0.2 with OpenDJ 2.6
We had a requirement to make the username editable. So, we ended up creating a custom ldap attribute called loginId and updating OpenAM config to use this attribute instead of uid.
When I import less than 4000 users, login works fine. When I import 4000+ users login doesn't work for any user, even 1 of the first 4000 users in the directory.
I can manually ldapsearch for the users and they exist in the directory, but I can't login with any of them.
We get an "Authorization failed!!" error, which is different to the usual username/password doesn't match error.
If anyone could shed any light on this, I would appreciate it.
Thanks
Edit
Here is the attribute definition I am now using.
attributeTypes: ( 1.3.6.1.4.1.37238.2.9 NAME 'loginId' DESC 'username (that can be updated)' EQUALITY caseIgnoreMatch ORDERING caseIgnoreOrderingMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 X-ORIGIN 'project schema')
I have rebuilt the indices and still having the same problem :(
That is probably because your instance of OpenDJ is configured to reject unindexed search request and you haven't defined and built an index for the loginID attribute.
