As far as I know there is no other implementation available to administer users, groups, acls, and domains for current Tamino databases. There used to be an alternative Java-implementation for some old version of Tamino available as shareware.
However the structure of the documents in ino:security is fairly simple, so it should not be too hard to write your own security GUI via the Java or PHP API.
