[Samba] How do I get Winbind accounts in LDAP?

If you're interested, Sun has told me that there is some kind of bug with
the way nsswitch.conf is dealt with in Solaris 9 but since nsswitch.conf is
not a pubic interface...blah blah blah they are still deciding whether they
should deal with it or not.  

In the mean time I'm still wondering how anyone else got this to work, this
bug can't only be affecting me?!

Does anyone have a working winbind pam.conf from Solaris 9 that I can look
at? 

Thanks,
Sap

You should get rid of the "winbind uid" and "winbind gid" parameters as they
have been superceded by "idmap uid" and "idmap gid".

Did you install the libnss_winbind.so module you built (it's in the
~samba/sources/nsswitch directory) as /lib/nss_winbind.so and link it to the
appropriate version name?

Have you modified in /etc/nsswitch.conf the following:

passwd: files winbind
group: files winbind


Do you obtain correct domain account information from:

	getent passwd

and

	getent group

You will need to install the LDAP admin password into your Samba secrets.tdb
file. The command that does that is:

	smbpasswd -w 'secret_password'

PAM provides authentication, NSS (name service switch) does Identity
resolution. It is the instrument that will permit the LDAP database to be
populated via winbind.

I hope this helps.

Cheers,
John T.
