In fact in base system mysql works well and /etc/pam.d content is the same. Anyway when I rename or remove these 2 files, mysql starts and run well, it seems there is no problems then. It is clear that it is connected with pam modules. I think I should do some debug when starting mysql as you said to find out where exactly is the problem... -- Edmunds aka Kalnz
