We have some issues with a kerberos on a samba client. Start process
is all right and user can connect to the linux boxes, but few hours
later it is not the case any more and I get the following error

in my /var/log/syslog on client side

message repeated 10 times: [ [LwKrb5GetTgtImpl
KRB5 Error code: -1765328161 (Message: Looping detected inside
Jul  8 12:23:48 ba-tec-06 lsass: [lsass] Failed to authenticate user
(name = 'usertest') -> error = 41956, symbol =
LW_ERROR_KRB5_GET_IN_TKT_LOOP, client pid = 15191

I have no errors on the server side. Few desktops face the issue and I
can't get the reason of the kerberos looping ticket.

Thanks for your help
