[Samba] loop kerberos client samba

[joseph-andre Guaragna]

Hi,
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
/builder/src-buildserver/Platform-8.2/src/linux/lwadvapi/threaded/krbtgt.c:276]
KRB5 Error code: -1765328161 (Message: Looping detected inside
krb5_get_in_tkt)]
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

Hi, not sure if this is the right place to ask about this problem, you
are using pbis and I am fairly sure 'LW_ERROR_KRB5_GET_IN_TKT_LOOP' is
an error message from pbis. I think 'LW' is short for likewiseopen, now
known as pbis.
