[Samba] winbind socket error

[Brannon King]

I'm attempting to authenticate domain users through httpd using winbind, and it is not working for me. I'm running FC4 on some older hardware with the 3.20 samba packages. My wbinfo commands all seem to work fine. I've tried these two /etc/pam.d/httpd files:

auth     required     /lib/security/pam_winbind.so debug
account  required     /lib/security/pam_winbind.so debug

and

auth     required     /lib/security/pam_smb_auth.so debug nolocal
account  required     /lib/security/pam_permit.so

The former gives me this in the messages log file:

Aug 30 14:50:55 sbs-linux-01 pam_winbind[2178]: Verify user `bking'
Aug 30 14:50:55 sbs-linux-01 pam_winbind[2178]: write to socket failed!
Aug 30 14:50:55 sbs-linux-01 pam_winbind[2178]: internal module error (retval = 3, user = `bking')
Aug 30 14:50:55 sbs-linux-01 httpd[2178]: PAM audit_open() failed: Permission denied

and the latter only gives me the last line of the above.

The httpd error log records this:

PAM: user 'bking' - not authenticated: System error

Any ideas? I have the firewall turned off. The log files in the log/samba folder seem to only record service up/down events. Is there some other log file I should look at? Thanks for any help.
