Hello Samba List,

I am currently running samba 3.3.2 joined to ADS and I am consistently
getting this error in the winbind log:
no backend defined for idmap config DOMAIN

Also, I seem to lose association between user and uid. I think it happens
when the winbind cache expires.

Here's my smb.conf:

        workgroup = DOMAIN
        realm = DOMAIN.COM
        server string = server
        security = ADS
        password server = *
        log level = 1
        log file = /var/log/samba/%m
        max log size = 50
        idmap uid = 16777216-33554431
        idmap gid = 16777216-33554431
        winbind use default domain = Yes
        winbind offline logon = false
        template shell = /bin/false
        local master = No
        dns proxy = no
        socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=8192
        unix extensions = no

        path = %H
        read only = No
        inherit permissions = yes
        inherit owner = yes
        browseable = yes

Thank you,
