ARS_LDAP_OD_AUTHORITY_FALLBACK parameter
Valid values are TRUE and FALSE.
If the value is set to TRUE and the user ID does not exist on the LDAP server for the bind attribute, the LDAP server authentication is bypassed. The logon process is reverted back to the normal Content Manager OnDemand logon.
This parameter is optional and defaults to FALSE if not specified.
Example:
ARS_LDAP_OD_AUTHORITY_FALLBACK=TRUE
