Currently we mount the samba shares, e.g. the home directory, using nfs. The test setup is that instead of: mount -t nfs hh1:/home2 /home2 -osec=rw,krb5 I changed to: mount -t cifs //hh1/home2 /home2 -osec=rw,sec=krb5,multiuser This works fine for console logins, but is very slow (unusable) for graphical logins to either LXDE or XFCE. The login sometimes works: Kerberos: AS-REQ ste...@hh3.site from ipv4:192.168.1.41:57380 for krbtgt/hh3.s...@hh3.site Kerberos: Client sent patypes: 149 Kerberos: Looking for PKINIT pa-data -- ste...@hh3.site Kerberos: Looking for ENC-TS pa-data -- ste...@hh3.site Kerberos: No preauth found, returning PREAUTH-REQUIRED -- ste...@hh3.site Kerberos: AS-REQ ste...@hh3.site from ipv4:192.168.1.41:41237 for krbtgt/hh3.s...@hh3.site Kerberos: Client sent patypes: encrypted-timestamp, 149 Kerberos: Looking for PKINIT pa-data -- ste...@hh3.site Kerberos: Looking for ENC-TS pa-data -- ste...@hh3.site Kerberos: ENC-TS Pre-authentication succeeded -- ste...@hh3.site using arcfour-hmac-md5 Kerberos: AS-REQ authtime: 2012-10-18T09:57:33 starttime: unset endtime: 2012-10-18T19:57:33 renew till: 2012-10-19T09:55:48 Kerberos: Client supported enctypes: aes256-cts-hmac-sha1-96, aes128-cts-hmac-sha1-96, des3-cbc-sha1, arcfour-hmac-md5, using arcfour-hmac-md5/arcfour-hmac-md5 Kerberos: Requested flags: renewable, forwardable Kerberos: TGS-REQ ste...@hh3.site from ipv4:192.168.1.41:50790 for host/hh7.hh3.s...@hh3.site [canonicalize, renewable, forwardable] Kerberos: TGS-REQ authtime: 2012-10-18T09:57:33 starttime: 2012-10-18T09:57:33 endtime: 2012-10-18T10:02:33 renew till: 2012-10-19T09:55:48 Kerberos: TGS-REQ ste...@hh3.site from ipv4:192.168.1.41:44350 for cifs/h...@hh3.site [canonicalize, renewable, forwardable] Kerberos: TGS-REQ authtime: 2012-10-18T09:57:33 starttime: 2012-10-18T09:57:33 endtime: 2012-10-18T19:57:33 renew till: 2012-10-19T09:55:48 But then as soon as we open the file manager (or do anything else) it freezes for as long as 5 minutes, before it makes another cifs request and comes alive for a while: Terminating connection - 'wbsrv_call_loop: tstream_read_pdu_blob_recv() - NT_STATUS_CONNECTION_DISCONNECTED' single_terminate: reason[wbsrv_call_loop: tstream_read_pdu_blob_recv() - NT_STATUS_CONNECTION_DISCONNECTED] Kerberos: TGS-REQ ste...@hh3.site from ipv4:192.168.1.41:58872 for cifs/h...@hh3.site [canonicalize, renewable, forwardable] Kerberos: TGS-REQ authtime: 2012-10-18T09:57:33 starttime: 2012-10-18T09:59:58 endtime: 2012-10-18T19:57:33 renew till: 2012-10-19T09:55:48 It is then OK for a few minutes more until it freezes again until the next cifs request etc etc. . .

Sorry, I'll join the list.
What kernel is the client running here?
