Crowd Connector to AD


i'm trying to connect my Crowd server to the company AD, i'm always getting 'authorization fail'.

Does the user I've entered in the connector must be an Admin on the AD container (OU)? (or READ permissions are enough?)

Also, the AD guys told me that the connection to the AD must be with Kerberos Ntlm protocol, Does Crowd supports that? (or there is no way i'm connecting it to our organization AD)

The user that you set while configuring the connector does not have to be an admin. Any standard user with read rights is enough.

The AD connector in Crowd uses standard username/password authentication for LDAP (or LDAPS). Though it is not supported by Crowd, LDAP requests to Active Directory can also be authenticated with Kerberos but I would be very surprised that your organisation forbids standard username/password LDAP (or LDAPS) authentication.  


Thanks for the quick answer, can you please explain what i need to do to authenticated with Kerberos while defining my connector?

(do i need to change my url from "ldap://...." to something else?)

Hi @lilach feit,

You can't do that as it is not supported by Crowd. As of today the LDAP connector in Crowd only allows you "bind" to AD with a username/password, not with a Kerberos ticket.

Can you explain the requirement again? The connection between crowd needs to be Kerberos/NTLM?

Hi Steve, 

It needs to be KERBEROS protocol 
NTLN is blocked in our network. 

Does Crowd supports KERBEROS protocol ? 
If so, please let me know what is the configuration required ?
