How can I know that, my application (using LDAP/exchange server and Exchange Web Service) supports LDAP over SSL?
I am new to this concept. I do not know the concept of SSL certificate too. Can any one explain me it in simple terms. Please reply as soon as possible. I need it to use.
Thanks In advance.
Your exchange admin needs to setup LDAPS which is the secure version of LDAP.
I got solution, here are the links...enjoy..

I have an openvpn CE running with slef certified signed certificates.
I wanted to add also Google LDAP functionnality.
So i did.
But its seems i cannot use anymore my old certificates as it asks for a Username/Password now there is LDAP configured.
Is there a way to have both authentication process working at the same time ?
Thx !
Maybe the question was not clear.
Is there a way to bypass LDAP Authentication for some users on OpenVPN CE ?
I want my network server to connect automatically, using certs, but not LDAP.
Thanks !
I am trying to workout how to configure a CXF consumer to use https, but use basic authentication.
I presume we need to attach our certificate using the httpj:engine-factory but whenever I try and do that the server generated the follwing error:
javax.net.ssl.SSLHandshakeException: null cert chain
EDIT: I believe what is happening is that the server is requesting a client certificate, but the client does not send one. For "One Directional" SLL, I don't think the server should be asking for a certificate from the client.
How do I prevent the server from requesting a client certificate?
Any assistance greatly appreciated.
You need to install certificate in your JVM trust store. Please go through below link:
How to solve javax.net.ssl.SSLHandshakeException Error?
It turned out to be quite simple. In the httpj:engine-factory, there is a setting for client authentication.
<sec:clientAuthentication want="false" required="false"/>
This controls whether the server requests a certificate from the client. I had copied this from samples with Bi-Directional SSL and these values were set to true.
I am trying to resolve a problem whereby trying to set a users password over LDAP is failing because of an access denied error - even though I am authenticating against the AD with an admin user.
An answer found in stackoverflow says that either I have to run the IIS user as the admin user (which does work) or i should connect to LDAP via SSL.
I cant go with the first option because I am using Elastic Beanstalk which will create and terminate instances so i cant change/set the user that IIS will be running as. So I am trying to use the LDAP over SSL idea.
My question is does that still require that the client itself also have a certificate installed in order to establish trust with the Domain controller? Or does this work just by installing a cert on the Domain controller and allowing the connection over SSL?
If it requires a certificate on the client then I have the same problem as i cant install anything on the client server other than the deployed app since Beanstalk is going to recereate and terminate that instance at will.
So does LDAPS require a cert on the client?
Is there a better way to solve my problem given the infrastructure i am using?
So does LDAPS require a cert on the client?
no, LDAPS do not require client certificate. Domain controller certificate is sufficient to utilize LDAPS. More details about LDAPS and certificate requirement: LDAP over SSL (LDAPS) Certificate

there might be over9000 reasons why you receive this message. You need to check whether you are successfully authenticated on DC, if yes, check whether you have permissions and privileges (especially, if UAC is enabled). I would set up audit policies (on failed user password changes) and check Security eventlog to figure out what is going wrong.
No.
For openldap, I achieved this by adding this line to ldap.conf. But be aware of that, when you do that, your connections will be open to attacks like man-in-the-middle or any other.
TLS_REQCERT never
This is what I found using trial and error approach:
Actually, LDAPS server always asks for client certificate. You can verify that by turning on SCHANNEL log and observing the following message:
If there is no client authentication certificate than LDAPS connection still succeeds, i.e. no client authentication certificate is required indeed. But if you have some invalid client authentication certificate (in my case it was an expired cert installed long ago by a third party app) the connection will fail w/o any error or warning in SCHANNEL log on the client side. It took me a while to figure this out.
Yes of corse your client need a certificate to allow ladps communication betwen
him and de server.
According to
windowsitpro.com:
As an option, you can use LDAPS for client authentication -- but doing so requires that you also install a client authentication certificate on each of your clients."
I don't know if someone is familiar with Tivoli Directory Server (ldap) but I guess there is something more or less the same in every ldap software.
So, there is a setting for ssl authentication which can be serverClientAuth and serverAuth. With serverAuth it is sufficient for the server to provide the certificate and the client (jxplorer) just accepts it to connect. With serverClientAuth except from the certificate provided by the server also the client needs to have its certificate on the server.
In my setup I have the serverClientAuth setting. So I was wondering if it is possible for jxplorer to provide the client certificate to the ldap server.
Any thoughts are welcome. Thanks.
Yes it is possible, and there is a menu provided specifically for that purpose, which lets you define they KeyStore, truststore, and various other SSL things.
Can anyone explain to me when a certifate is require using WCF and authentication. From my understanding although i could be way off :-)
basichttp doesn't require a certificate to do authentication is hosted in IIS and using SSL otherwise a certificate is required
All other bindings like netTcpBindings etc require the use of certficate - is this true?
Or does it depend on what type of authentication i am using?
I would really appreciate any info or maybe a table telling me when a certifcate is needed.
I have a number of scenerios i am investigating like hosting in IIS or hosting in WIndows Service..
And i just can't seem to find the info i need
THanks in advance
There are two scenarios where you need a certificate:
A server side certificated that is used for SSL. For basichttpbinding, if you are sending a username and password over the network you should use SSL.
A client side certificate if you are authenticating clients using certificates.
Other bindings may use machine keys and certificates in the operating system, but you do not need to install a certificate for them to work.
