Actually, this extension is so super, that you can turn off standard Joomla Authentication and any Email Authentication plugins. Enjoy!
- Added check for banned users. Now you may set to block users, that were banned on forum.
P.S.: It definitely should work with IPB 3.x, but I can't guarantee the same for IPB 2.x
Feel free to contact me via email, given on demo site and in extension file header.
Using it on Joomla 2.5.4 and IPB 3.2.3.
When you create a account with IPB, you can then also login to joomla with this username & password.
When looking in the user-table of joomla (administrator) you can see that if a user exist in IPB the user will be added as a registered member. (after a successful login).
Good work Dev.
Maybe some more functions?
