You will need to code a pair of functions, viz.
   string function _username_hook_frombackend(string $userID)
   string function _username_hook_tobackend(string $uid)
Cf. horde/config/hooks.php.dist

As you probably can read German, please feel free to ask, privately,
for my horde/config/hooks.php, which has an example of these (and
some other) functions, commented thoroughly, in German.

Good luck,
