Do you have winbind in nsswitch.conf ?

With this configuration 'account' can only succeed when USER is available over NSS calls. Please make sure "getpwnam USER" succeeds and reopen if this still an issue. (I verified this works with 3.0.23rc2).

In nsswitch.conf is there

passwd: compat winbind
group:  compat winbind
shadow: compat winbind

And I Cannot execute "getpwnam" 

In which rpm is  this command "getpwnam"?

* do not tweak the the 'auth methods' parameter.

This is a configuratio issue as far as I can tell and not a bug.
Please post to the mailing list for help.
