Hello List, I have a little question regarding the kerberos ticket thing when installing samba with option security = ads. Please could anyone explain to me this system im general. Everything I know is, that i have to fetch a ticket at the KDC, so that i can do a net join. After this my samba is visible in the "Computers" section of the AD. And the Winbind daemon can fetch the users, groups and all that stuff. But after 10 hours my ticket expires. Does this have any effect on the communication between the samba server and the ADS? Or is the ticket only neccesary for the net join and then it isn't used any longer? I ask these questions cause i got some really weird messages some days ago (after the ticket was expired), which wet away after i fetched a new ticket. And restartet the smb and winbind daemon. But now it seems to work since two days without renewing ticket or fetching a new one. I can't find any detailed information about this kerberos ticket thing... So if you have got a nice manual about the process of taking the ticket, joining a ads and so on... please let me know where i cant get this one. TIA Michael
