This is a long thread with a lot of the same issues I have been having TRYING to get the SMF bridge with mod_joomla_smf_login_1_4_1 working over the past THREE days.
Here is my configuration:
Joomla 1.0.8
SMF 1.1-rc2
joomla-smf 1.1.02
mod_joomla_smf_login_1_4_1
PHP 5.0.5
Apache/1.3.36 (Unix)
mysql 4.1.18
The patch and mod install run fine. But if I use the mod_joomla_smf_login_1_4_1 - I ALWAYS get the "Incorrect username or Password. Please try again." message when I try to login. (I can get to Administration GUI fine) I finally started looking into the code and right off see problems with the doMamboSMF() function in /administrator/components/com_smf/functions.smf.php.
I see 2 variables used within the function that are not declared. #1 is "$data" and the other is "$err". I thought it was a problem with my register_globals being set on - so i set them off - but still the same problem.
If you look at the switch case statements - how would any of them be executed if the switch statement itself (isValidUser($data, $username, $password)) ALWAYS returns false (because $data is unknown)

That explains why I always get the _LOGIN_INCORRECT alert that is after all the switch options.
After 4 years of struggling with phpNuke and the zillions of bugs introduced by hundreds of mods and hacks to the core code over the years - and no one to step up and fix the core code - I switched to Joomla a few weeks back because I was impressed by the professionalism of what appeared to be an organized project team. I'm starting to have my doubts and fear it will be right there with phpNuke in no time - but that's another topic in itself.

p.s. sorry for letting off steam - I'm just an old 50+ burned-out programmer who's sat in a house with broken AC all weekend in 85 degree weather trying to get the family website (that I promised would be running before the holiday) up and running again.
