If you right click on Messenger services in C1 we have a default policy and Default scope but no Ldap policy. We constantly get LDAP related errors in the server console Like "host is unknown to system" "unspecified Ldap error occured" and "ldap doesnt understant Attribute"

Would adding a LDAP policy fix our LDAP headache or cause more headache? We have seen in the past with LDAP that if people have aliases in the tree ldap wont let them authenticate. Will this happen to us again with IM if we use an LDAP policy?
