Cannot logon using remote LDAP authentication. This occurs because LDAP with user-template configured uses the user-template value as the distinguished name (DN) for the LDAP search, instead of a properly formed X.500 name, for example: cn=xxx,ou=xxx,dc=example,dc=org


Remote LDAP authentication users are unable to login. Note: The user-template value is not a valid DN.


-- LDAP authentication configuration includes the user-template value as the DN. -- Attempt to logon.


You can use either of the following workarounds: -- Create a specific user for bind by configuring bind-dn and bind-pw, and remove user-template. -- Switch to local authentication.
