LDAP Server Information Configuration via Domain as recommended by Microsoft in CUCM

A customer wants to use best practice of Microsoft which means that he don't want to configure the LDAP and NTP Server on the CUCM with IP/Hostname/FQDN. He wants to configure just the domain here.


To make it more concret: In the Unified CM Administration on the CUCM under System->LDAP->LDAP Directory->LDAP Server information he does not want to configure the IP of the DC (x.x.x.x) he wants to configure the Domain (e.g. domain.com) to talk to the DC's. Same counts for the LDAP Authentication and for the NTP Servers configuration.

    FQDN should work in those fields, instead of IP Address
