lost phpmyadmin password, can"t do backups!

hello,
I'm trying to run a backup on a bitrock install sugarcrm on linux.
apache is running on port 8888, i try to get into phpmyadmin but it
asks for user and password.
I don't know what the user/password is. I saw user file so i know user
= administrator.
but I don't know password.

I have access to the httpd.conf file. I see the last part of the file
concerns authentication for phpmyadmin. Is there a way to turn off
authentication? I just need to get a backup.

I also try to use the command line but i get error 2202. it can't read
the /tmp/mysql.sock file.

i know mysql works because sugarcrm works fine from a browser.

Thanks,

Oskar
