If you run passwd to change a password, I get the following error on solaris systems (I am using samba 3.0alpha15): Supported configurations for passwd management are as follows: passwd: files passwd: files ldap passwd: files nis passwd: files nisplus passwd: compat passwd: compat AND passwd_compat: ldap OR passwd_compat: nisplus Putting the winbind in /etc/nsswitch on the passwd: and group: line causes this. This is a big problem. David David E.
