You have configured the Symantec Endpoint Protection Manager(SEPM) to use Active directory server for importing OU's and Authentication.
You have several Active Directory groups already synced, though when you change the directory server configuration in SEPM to LDAP, and attempt to sync, you receive the following error.
Failed to synchronize with the Directory Server <server name>
Check the directory server settings in the management console, and try again. [0xe0220000]
Release : 14.3 RU4
Component :
When Active Directory configuration is selected, the imported OU is associated with the full DN. However when LDAP is configured and LDAP BaseDN is specified, the DNs are repeated, resulting in an LDAP search failure.
Remove the LDAP baseDN information in the directory server configuration in SEPM
