Hello, as for my first post, I'd like to say HI to everybody. I find this page most usefull. I work as an IT technician in radio station ČRo Regina and I just had the idea to make a Samba domain controler for our network. I try folow the basic procedure from O'Reilly's book, but I encounter this problem. Code: pc245rp:~# smbpasswd -a jirka New SMB password: Retype new SMB password: Failed to modify password entry for user jirka I've been googlin' a lot, but I'm just amateur in Linux universe and I don't know what should I be looking for exactly. My configuration: Debian 5.0.3 Samba 3.2.5 So far installed openssh server so I can control my server with Putty and Midnight Commander. SWAT is also activated and I find it the best way to configure stuff, but adding a user for smbpasswd in SWAT doesn't work either. Would you people give me some hints and tips how should I proceed next with configuring my Samba as a Domain Controler? Thanks in advance! PS: I'm logged as root!
