Hi all, By some days around 12:00 o'clock I have the following problem with my SUSE Linux 2.6.11.4-21.9-default i686 i386 GNU/Linux, with Samba Version 3.0.21a-0.1-SUSE: xxx:~ # tail /var/log/samba/log.machine01 [2006/02/23 12:05:54, 1] smbd/sesssetup.c:reply_spnego_kerberos(180) Failed to verify incoming ticket! [2006/02/23 12:06:04, 0] tdb/tdbutil.c:tdb_log(772) tdb(/etc/samba/secrets.tdb): tdb_lock failed on list 2 ltype=1 (Interrupted system call) [2006/02/23 12:06:04, 0] tdb/tdbutil.c:tdb_chainlock_with_timeout_internal(82) tdb_chainlock_with_timeout_internal: alarm (10) timed out for key replay cache mutex in tdb /etc/samba/secrets.tdb [2006/02/23 12:06:04, 1] libads/kerberos_verify.c:ads_verify_ticket(336) ads_verify_ticket: unable to protect replay cache with mutex. [2006/02/23 12:06:04, 1] smbd/sesssetup.c:reply_spnego_kerberos(180) Failed to verify incoming ticket! By this moment, nobody can access to /data dir instead people already authenticated continuing working without any problem. The only solution is to restart winbind daemon. How can I fix it? Is probably "/etc/samba/secrets.tdb" a corrupted file? Following my smb.conf: [global] dos charset = 850 unix charset = ISO8859-15 display charset = ISO8859-15 workgroup = WORKGROUP realm = DOMAIN.SUB.COM server string = XXX security = ADS auth methods = guest, sam_ignoredomain, winbind:ntdomain password server = SRV01.DOMAIN.SUB.COM SRV02.DOMAIN.SUB.COM log level = 1 log file = /var/log/samba/log.%m max log size = 50 socket options = TCP_NODELAY SO_KEEPALIVE printcap name = cups domain master = No passdb expand explicit = No idmap uid = 10000-20000 idmap gid = 10000-20000 winbind separator = / admin users = xxx map acl inherit = Yes cups options = raw [data] comment = Linux-Fileserver path = /data read only = No create mask = 0770 directory mask = 0770 hide unreadable = Yes [printers] comment = All Printers path = /var/tmp create mask = 0600 printable = Yes browseable = No Thanks.
