[Samba] winbind and compat mode in nsswitch.conf

[Andy]

Hay together,

is the following entry in nsswitch.conf possible ?

passwd: compat
passwd_compat: winbind

I want to use the compat mode, so i can use the +/- semantic.
But in this case i cant login with username/password.

If i configure the nsswitch.conf like:

passwd: files winbind

The login works, but so i cant use the +/- semantic.

Andy ideas ?

Thanks,

Andy
