Description:
Authentication to CA Service Desk Manager may get slow when you use EEM integrated with Active Directory
Solution:
Usually the response improves if you change the default Active Directory port 389 to Global Catalog port 3268.
A Global Catalog server is a domain controller that stores extra information; its database stores objects for the forest instead of objects only the one domain.
The objects that occur in domain directory partitions other than the local domain partition hold only a subset of attributes for each object which make the LDAP queries faster.
