LDAP realm with Active Directory

Question

Hello,
In the sun one app server admin console i have set the security role to LDAP.
I have set up security roles in my web.xml such as this:
<security-role>
<description>This role represents administrators of the system, see actor administrators</description>
<role-name>administrators</role-name>
</security-role>
..and mapped the roles to groups in sun-application as follows:
<security-role-mapping>
<role-name>administrators</role-name>
<group-name>CMS_PM</group-name>
<principal-name>rlancett</principal-name>
</security-role-mapping>
My user and group information is stored in Active Directory so I have tried to configure the ldap realm in the admin console to get it working. These are the settings i have put in:
directory: ldap://earth.tier2consulting.com:389
base-dn: cn=Users,dc=tier2consulting,dc=com
jaas-context: ldapRealm
search-bind-dn: cn=administrator,cn=Users,dc=domain,dc=com
search-bind-password: ******
search-filter: sAMAccountName=%s
I get the error message :javax.naming.AuthenticationException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C09030B, comment: AcceptSecurityContext error, data 525, v893
WARNING: va:850)
FINEST: JAAS authentication aborted.
INFO: SEC5046: Audit: Authentication refused for [administrator].
I am pretty stuck on this having looked arounds all the forums:
Has anyone got sun one app server using Active Directory to get user/group information for security roles?
Thanks.

Howdy,
I don't have a solution to your problem, but maybe this tid-bit will help in debugging with Active Directory error messages. I'm new to AD, so excuse me if everyone already knows this, but...
The error message you get back from the directory contains an error code in hexidecimal:
LDAP: error code 49 - 80090308: LdapErr: DSID-0C09030B, comment: AcceptSecurityContext error, data 525, v893
If you translate '525' from hex to decimal you get '1317' which is the error message you can look up here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/base/system_error_codes.asp
1317 - ERROR_NO_SUCH_USER - The specified user does not exist.
It took me a while to find this tip, so I thought I'd share it. Oh, and the easy way to get decimal from hexidecimal is:
System.out.println( "Here is 525 in decimal: " + Integer.parseInt("525", 16));
Okay, hope this helps somebody.
Now it's up to you to find out why it can't find the administrator!
