User Sync (Gallery2 + Wordpress & Joomla)

I have three installations. Wordpress 2.6.2, Joomla 1.0.15, and Gallery 2.2.5. The Wordpress is installed in the site’s root and the Joomla and Gallery occupy their own subdirectories. I am using Gallery 2 Bridge 2.0.14 Beta in Joomla to embed Gallery, and likewise in Wordpress I’m using WPG2 3.0.7 for a Gallery embed. The two embeds are pointing to different sections of the gallery.

The problem seems to begin with Joomla. I want registered users to be able to see the full-sized Gallery images, and non-registered users to only see thumbnails. In the future I’d even like registered users to be able to upload images to specific albums. But I’m getting ahead of myself. As a single user initially logs in, Gallery reports that a user with the same Username, Full Name, and E-Mail has been created. However, neither the Gallery 2 Bridge or the WPG2 indicates this is so.

Gallery 2 Bridge tells me “User doesn't exist in Gallery 2 or isn't mapped,” with the appropriate grayed-out symbol beside it. And WPG2 simply doesn’t see the Gallery users, though I’m not positive if it’s meant to sync Gallery users to WP – it definitely does the converse.

So actually, up to this point, there hasn’t been a problem. This is a perfectly livable solution, except I get the sense that things are not right. I want Gallery 2 Bridge to recognize that Joomla users are in Gallery, so I press the “Sync” button in the upper-right of the administrator’s panel.

(The system lags on the processing of users – it never makes it past 1 – if there is even a single name shared between the Joomla users and the Gallery users. If WPG2 is active at the time of the sync, the Wordpress embed becomes corrupted and spits out error code until the newly added users have been excised from Gallery.)

After the sync all Joomla users have been added to Gallery, but Gallery 2 Bridge still doesn’t see any of them, and I have gotten nowhere. So if somebody could clue me in why users in Joomla are not being recognized as being in Gallery also, please do so!
