Hello everybody,
we're trying to set-up Samba to share directories with Win users from some Linux servers. We've set up kerberos, gotten a ticket, joined the server to the domain, we get correct users/groups from "wbinfo" and "getent". The problem lies in "id": it does not update its user<->group mappings when they change on AD, even if "wbinfo" and "getent" get the changes. If we erase the /var/lib/samba/*.tdb cache the mappings get updated, but I guess this should not be the case, they should update automagically. A thing we've noticed is that "net rpc info" on all our DCs always returns "1" as the "sequence number". We've tried this configuration with centos original rpms and with EnterpriseSamba rpms for centos.


krb5.conf:

       [logging]
         default = FILE:/var/log/krb5libs.log
         kdc = FILE:/var/log/krb5kdc.log
         admin_server = FILE:/var/log/kadmind.log

       [libdefaults]
         default_realm = AAA.LOC
         dns_lookup_realm = false
         dns_lookup_kdc = false
         ticket_lifetime = 24h
         renew_lifetime = 7d
         forwardable = true
       # default_tkt_enctypes = des3-hmac-sha1 des-cbc-crc
       # default_tgs_enctypes = des3-hmac-sha1 des-cbc-crc

         AAA.LOC = {
          kdc = addc01pl.aaa.loc
          kdc = addc02pl.aaa.loc
          admin_server = addc01pl.aaa.loc
          default_domain = AAA.LOC
         }

       [AAA.LOC]
         .aaa.loc = AAA.LOC
         aaa.loc = AAA.LOC

lmhosts:

   127.0.0.1    localhost
   192.168.0.250    AAA

smb.conf:

       [global]
       workgroup = AAA
       realm = AAA.LOC
       netbios name = BBB
       dns proxy = no
       log file = /var/log/samba/log.%m
       max log size = 1000
       syslog = 0
       security = ads
       domain master = no
       idmap uid = 10000-20000
       idmap gid = 10000-20000
       #map untrusted to domain = yes
       winbind use default domain = yes
       client ntlmv2 auth = yes
       interfaces = eth2 lo
       bind interfaces only = yes
       #log level = 3
       winbind enum users = yes
       winbind enum groups = yes
       winbind cache time = 60
       password server = 192.168.0.250, 192.168.0.251
       max protocol = SMB2
       load printers = no
       printing = bsd
       printcap name = /dev/null
       show add printer wizard = no
       disable spoolss = yes
       idmap cache time = 1
       idmap negative cache time = 1

Thanks for all the help we can get! (we've been reading and trying lots of things on forums/mailinglists, but to no avail).
