Hey List- Since samba is in the middle..trying here first. I have a samba FreeBSD box as just a member server which was authenticating against a samba PDC. For other reasons we migrated that to a Win2003 ADS box. I got the member server to join the ADS domain and users who are logged in can browse the shares, etc... without issue. The problem I have is that proftpd (via PAM) is no longer authenticating domain users. Here is my smb.conf: [global] workgroup = DOMAIN realm = int.DOMAIN.com netbios name = DOMAINTEST #server string = Samba %v on %L server string security = ADS password server = DOMAINSERVER wins server = 10.0.0.3 encrypt passwords = yes idmap uid = 15000-20000 idmap gid = 15000-20000 #winbind use default domain = yes #winbind separator = \ #winbind nss info = sfu guest ok = yes follow symlinks = no case sensitive = no os level = 33 I was getting the following error: [2007/07/19 05:46:21, 0] nsswitch/winbindd.c:request_len_recv(544) request_len_recv: Invalid request size received: 1848 but a reboot and a library reload has cleared that up. My proftpd pam file (hasn't changed) looks like: #PAM config file for ProFTPD auth required /usr/local/lib/pam_winbind.so account required /usr/local/lib/pam_winbind.so I changed the debug lvl to 10 and I can see the server doing a request for the FTP user and it doesn't throw any obvious errors. I am logging into proftpd using DOMAIN\ftpuser Thoughts? Henrik -- Henrik Hudson lists@rhavenn.net ------------------------------ "God, root, what is difference?"
