check group membership is sometimes case sensitive

"AuthLDAPRemoteUserAttribute uid
AuthLDAPGroupAttribute memberUid
AuthLDAPGroupAttributeIsDN Off
AuthBasicProvider ldap

require ldap-group cn=Domain Admins,ou=Group, dc=DOMAIN,dc=de"

memberUid is not case insensitive (memberUid from
posixGroup, which is also used by samba domain groups).
