Description
LDAP import from a non standard LDAP server times out and fails to load the data.
Cause
This happens if the LDAP server doesn't support Paging but 'Paging' is enabled on the LDAP server record.
Resolution
Disable 'Paging' from the LDAP server record and load the data again. This will import the data using the Nibbling feature.
