Active Directory Login failure on Blackberry Administration Server (BAS) – The username, password, or domain is not correct. Please correct the entry.

Posted on July 24, 2012

Logging into BAS can fail if DNS records are incorrect or stale.
Before we get into that, I highly recommend you look through your BAS logs to analyse the error.

1) Try to login to the BAS admin service using your LDAP/Active-Directory credentials several times. This will register a few errors in your logs that you can track down.
2) Head to: C:\Program Files (x86)\Research In Motion\BlackBerry Enterprise Server\Logs\(TODAYS DATE)\
3) Open the log file that starts with "SERVERNAME_BBAS-AS-" (Make sure it's the most recently modified version!)
4) Scroll to the bottom and look for lines that start with "(XX/XX XX:XX:XX:XXX):{http-"

(XX/XX XX:XX:XX:XXX):{http-URL.COM%2F10.100.1.36-3443-5} [com.rim.bes.basplugin.activedirectory.LDAPSearch] [INFO] [ADAU-1001] {u=SystemUser, t=30847} performPagedLDAPSearch problem performing LDAP operation: url=ldap:// base= filter=(&(objectClass=user)(objectCategory=person)(|(sAMAccountName=besadmin)(userPrincipalName=besadmin))) scope=2

If you see a message similar to this, BAS is trying to grab a Kerberos ticket and your DNS is causing errors.


1) Load your Active-Directory DNS management console.
2) Verify that you have reverse DNS setup for the entire domain. You require PTR records (reverse dns records) for each of your domain controllers. If you don't have them, FIX THIS!
3) Verify that you have no stale records pointed to decommissioned or retired domain controllers. Drill down into each DNS folder and confirm the hostname and IP match your current infrastructure. It's amazing how many stale records we find.
4) Once repairs are made to the DNS settings, right click the server name in the DNS management and "clear cache"

Reboot your BES server just for fun, and try to login.
