YaST mail server module missing ldap support after upgrade from SLES 11 SP4 to SLES 15

This document (000019719) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server SLES 15 SP2
SUSE Linux Enterprise Server SLES 15 SP1
SUSE Linux Enterprise Server SLES 15
SUSE Linux Enterprise Server SLES 11 SP4

Situation

After upgrading, attempting to start the YaST2 mail server configuration module results in the following popup:

The setting MAIL_CREATE_CONFIG is turned off. You have
probably modified the configuration files directly.
If you continue, it will be turned on and
Config Postfix will overwrite manual changes.
         [Cancel]           [Continue]

Resolution

Do NOT continue, continuing will destroy the LDAP integration for postfix.

LDAP related configuration for postfix is no longer possible with YaST. The old configuration will still continue to work, but can no longer be changed/edited via YaST !

If already done, it is needed to restore the SLES 11 SP4 postfix configuration /etc/postfix/* from backup. Configuration changes need to be made manually in configuration files directly going forward.

Cause

LDAP support has been removed from the YaST2 mail server configuration module.
