Hi,
i have a permanent problem with my samba members. there lost after some times his connections to DCs and i need to restart winbind.
Also same problem with winds client that running 24x7. After few days i can not logged in.
i think thats a problem with kerberos tickets.
i have checks samba logs and found that samba member and windows client ask for new tickets and get new expiration.
in my DCs i have set
kdc:service ticket lifetime = 1
kdc:user ticket lifetime = 24
kdc:renewal lifetime = 120
and Master krb5.conf looks
[libdefaults]
default_realm = HQ.KONTRAST
dns_lookup_realm = false
dns_lookup_kdc = true
ticket_lifetime = 1d
renew_lifetime = 5d
[realms]
HQ.KONTRAST = {
kdc = vl0227.hq.kontrast
kdc = vl0230.hq.kontrast
kdc = pl0231.hq.kontrast
master_kdc = vl0227.hq.kontrast
admin_server = vl0227.hq.kontrast
}
[domain_realm]
.hq.kontrast = HQ.KONTRAST
hq.kontrast = HQ.KONTRAST
[logging]
kdc = SYSLOG:INFO:DAEMON
admin_server = FILE:/var/log/kadmind.log
So what i saw was GPOs are default empty. i need for winbind configure Kerberos Policy?
kind regards
