Hi All, Debian Lenny, with Samba 3.4.8~dfsg-2~bpo50+1 (backports)
I'm having an issue where 1 or 2 random clients out of 100 seem to be disconnected from a samba print server and not allowed to reconnect until they log off and back on to their machines. It is not always the same clients. I have a Samba fileserver running on another machine with virtually identical config that does not have this issue. This happens pretty quickly after the ads_cleanup_expired creds log: --------------- [2010/11/25 15:15:01, 3] libsmb/clikrb5.c:620(ads_cleanup_expired_creds) ads_cleanup_expired_creds: Ticket in ccache[MEMORY:cliconnect] expiration Fri, 26 Nov 2010 01:14:44 GMT --------------- In the specific client logs after this occurs I get the following: --------------- [2010/11/25 15:17:15, 0] lib/util_sock.c:738(write_data) [2010/11/25 15:17:15, 0] lib/util_sock.c:1491(get_peer_addr_internal) getpeername failed.

It doesn't seem to be something wrong with my samba config, because it works 99% of the time. But please find it below and advise if anything might be causing this. --------------- [global] security = ads workgroup = DOMAIN realm = DOMAIN.LOCAL password server = dc1.domain.local, dc2.domain.local encrypt passwords = yes server string = domainprint netbios name = domainprint idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes winbind use default domain = yes winbind offline logon = yes enhanced browsing = no template shell = /bin/false veto files = /TheVolumeSettingsFolder/, /Temporary Items/, /*DS_Store*/, /*AppleDB/, /*AppleDesktop/, /*AppleDouble/, /Network Trash Folder/, * /*Trashes/, /*TemporaryItems/, /*FBCLockFolder/, /*FBCIndex/ delete veto files = yes create mask = 0775 directory mask = 2775 invalid users = root panic action = /usr/share/samba/panic-action %d log file = /var/log/samba/log.%m log level = 3 socket options = TCP_NODELAY printing = cups printcap = cups #load printers = yes printer admin = @DOMAIN\itdept follow symlinks=yes ----------------- Is it possible to change the ticket expiration time? or is there a Windows setting on the Domain controller than needs to be changed? (Windows server standard 2008 R2). Any help appreciated, Please advise if I need to post any other details.
