Netbackup 52XX Appliances LDAP issues and questions

I have successfully enabled UNIX LDAP authentication on both our 5220 and 5230 appliances, I have noticed the following issues and was wondering if anyone else is seeing these issues.
 
Have seen these issues on both the 2.6.0.1 and 2.6.0.3 releases.
 
1.  After authorizing user accounts as Administrators, some users can log in via ssh successfully, some will be able to log in, but get a command prompt instead of the CLISH menu, while others the ssh session hangs.
 
2. Running LDAP commands from the CLISH menu (settings->security->authentication->LDAP->list) takes an hour to return results.
 
3.  The Web GUI successfully shows the LDAP Server configurations, but will not show configured users.   I know they are configured as the CLISH commands will show the configured users after an hour.
 
4.  All of the added LDAP user accounts are authorized as Administrator, when Logging onto a Java GUI, some users will be denied, others get all the options available, while others will only get the Backup,Archive,Restore control.
 
With the release of 2.6.0.3 it now includes the option of authenticating using Active Directory,  has anyone been able to successfully set that up and use it.  I can authenticate the appliance to our Domain, and add my user ID, after that I can not add additional id's to the appliance. In addition, sometimes when logging on as the local admin account I will get "user not authorized".
 
Any feedback with experience using using LDAP or Active Directory Authentication on the Netbackup 52XX Appliances would be appreciated.
