We are using winbind on AIX, and this is my documentation on how I got
it to work:


cp -p /opt/pware/samba/3.0.28/lib/security/WINBIND /usr/lib/security

edit /usr/lib/security/methods.cfg and add

        program = /usr/lib/security/WINBIND
        options = authonly

edit the default stanza in /etc/security/user to have

        SYSTEM = "WINBIND OR compat"
