Hello,

the last two days i have problems with my AD group which is defined in share
setting valid users

Winbind looks to lost mapping of this group and so no user can connect to this
share anymore.

When restart winbind service mapping works again until mapping lost again.


ls -lsa shows me in issue this:

        2      4 drwxr-x---  63 root               12001
4096 Feb  4 23:42 Share

After restarting winbind:

        2      4 drwxr-x---  63 root               group_intern
4096 Feb  4 23:42 Share


My smb.conf looks like


[global]
       netbios name = MEMBER1
       security = ADS
       workgroup = HQ
       realm = hq.internal

       log file = /var/log/samba/%m.log
       log level = 1

       dedicated keytab file = /etc/krb5.keytab
       kerberos method = secrets and keytab
       winbind refresh tickets = yes

       winbind trusted domains only = no
       winbind use default domain = yes
       winbind enum users  = yes
       winbind enum groups = yes
	winbind cache time = 300


       idmap config *:backend = tdb
       idmap config *:range = 500-9999

       # idmap config for domain HQ
       idmap config HQ:backend = ad
       idmap config HQ:schema_mode = rfc2307
       idmap config HQ:range = 10000-99999

       # Use settings from AD for login shell and home directory
       winbind nss info = rfc2307

[Share]
   path = /data/share
   browseable = yes
   writeable = yes
   force group = Group_Intern
   valid users = @Group_Intern
   create mask = 0660
   directory mask = 0770
   #oplocks = 0
   vfs objects = full_audit recycle
   full_audit:prefix = %u
   full_audit:success = mkdir rename rmdir unlink pwrite
   full_audit:failure = none
   full_audit:facility = LOCAL5
   full_audit:priority = NOTICE
   recycle:versions = yes
   recycle:exclude = .*, ~*



Anyone has an idea for this problem?


Regards
Oliver
