|Configuring User Authentication / Configuring LDAP Directory Service|
GemFire XD does not support LDAP groups.
For performance reasons, the LDAP directory server should be in the same LAN as GemFire XD. GemFire XD does not cache the user's credential information locally and thus must connect to the directory server every time a user connects.
Connection requests that provide the full DN are faster than those that must search for the full DN.
