[cisco-voip] CUCM LDAP Authentication to multiple AD Forests

[Andy]

Hi,
I'm wondering if anyone has got some pointers for this.
We have a 9.1.2 cluster and the customer has multiple AD forests, which 
is ok for getting users into Corporate Directory, but not it would seem 
for actually getting the users to authenticate when they login to say 
ccmuser or webex on premis.
There is a trust between both AD forests as the users can login to pc's 
whereever they like, but Callmanager logins fail.
The users who are in the Authentication OU in Ad are fine.
I have raised a TAC, but I thought that someone else may have come 
across this before, whilst I wait for TAC to respond.
