User Synchronization(MediaWiki)

I'm currently trying to integrate login sessions with mediawiki... and I can't seem to get the galleryembed functions to work properly.

Doing a simple embedded page where I call init and handlerequest with a blank user ID works fine.

For one, the whole externalidmap thing seems unresponsive. addExternalIdMapEntry didn't do anything.. I tried manually entering a mapping for a current user and that didn't work out either.. the data type of entityType is an integer in the database so I'm not sure what it expects when I pass it "GalleryUser".. Whenever I try and pass a mapped user id while init'ing the gallery page I get error unable to find object <uid> GalleryUser. I'm not sure how it'll ever find something mapping to GalleryUser since all I can store in the database entry is an integer since I can't find an entitytype->integer definition.

Error (ERROR_MISSING_OBJECT) : 1 GalleryUser

But onto freshly created users... I call createUser in the mediawiki hook and nothing happens at all. Just hangs there and nothing ever gets written to the gallery2 database or mediawiki database.

function addUser($user, $password)
{
GalleryEmbed::createUser($user->mId, array('username' => $user->mName,
'email' => $user->mEmail,
'fullname' => $user->mRealName,
'hashedpassword' => $password,
'creationtimestamp' => $user->mRegistration));
return true;
}

Any ideas on how to approach any of this? Help is appreciated.
