[Samba] User names longer than 8 characters

[Octavio Alvarez]

Hello.

I set up my samba server and added two users, "alvarezp" and "lunablack".  
The first one works, but the second one gives Access Denied errors.

I already tried to map "lunablack" to "luna" via 'username map', with no  
luck.

Both passwords are under or equal 8 chars long.

Here is some info:

# from 192.168.0.65 (192.168.0.65)

# Global parameters

I'd appreciate any help.
