An activated synchronization profile deletes a user account from OneSpan Authentication Server Appliance if it has the Distinguished Name attribute, but the corresponding user account cannot be found on the LDAP server. This may occur under the following circumstances:
- The user account has been removed from the LDAP server.
- The user account on the LDAP server has been moved from the search base defined in the profile.
- The user account on the LDAP server has been changed and does no longer match the profile's filter.
- The synchronization profile settings have been changed, e.g. the search base or filter entries.
