I have a kerberos ticket, I have pam_krb5 configured, and yet, I can't login through kerberos. This works: smbclient -U user -W G -L //foo.com/bar This doesn't: smbclient -U user -W G -L //foo.com/bar -k This is with -d3 --- lp_load_ex: refreshing parameters Initialising global parameters rlimit_max: rlimit_max (1024) below minimum Windows limit (16384) params.c:pm_process() - Processing configuration file "/etc/samba/smb.conf" Processing section "[global]" added interface eth0 ip=fe80::216:41ff:fee3:8ae0%eth0 bcast=fe80::ffff:ffff:ffff:ffff%eth0 netmask=ffff:ffff:ffff:ffff:: added interface eth0 ip=172.21.41.66 bcast=172.21.41.255 netmask=255.255.254.0 Client started (version 3.5.4-63.fc13). tdb(unnamed): tdb_open_ex: could not open file /var/lib/samba/gencache.tdb: Permission denied resolve_lmhosts: Attempting lmhosts lookup for name foo.com<0x20> resolve_wins: Attempting wins lookup for name foo.com<0x20> resolve_wins: WINS server resolution selected and no WINS servers listed. resolve_hosts: Attempting host lookup for name foo.com<0x20> Connecting to 10.x.x.x at port 445 Doing spnego session setup (blob length=124) got OID=1.2.840.48018.1.2.2 got OID=1.2.840.113554.1.2.2 got OID=1.2.840.113554.1.2.2.3 got OID=1.3.6.1.4.1.311.2.2.10 got principal=not_defined_in_RFC4178@please_ignore cli_session_setup_spnego: got a bad server principal, trying to guess ...

please reopen if this still happens with supported samba releases. I assume the problem is gone.
