Novell ZENworks 7 Desktop Management Support Pack 1 - ZDM7 SP1 Middle Tier


The customer installed the ZENworks Middle Tier service on a Windows 2003 server that was also a Domain Controller.
Since AD was using the default LDAP port of 389, eDirectory's LDAP was configured to use port 1389 for clear-text access and 1636 for secure LDAP.
The customer confirmed LDAP was operational on port 1389 using an LDAP Browser.
The customer also confirmed that"HKLM\Software\Novell\XTier\Configuration\XSrv,LDAP Port" was correctly configured for the clear-text port of 1389.


The middle tier server will attempt LDAP contextless login lookups using clear-text if it is configured to use ports 289-489.
If a port outside of this range is used then LDAP contextless login will attempt to use secure LDAP.
The customer was able to resolve the issue by using port 1636 which allowed the secure LDAP to function properly.
The customer would also have been able to configure eDirectory to use port 390 for clear-text and configure middle tier to use this port number.
