Dear list, after 2 weeks running Samba 3.0.26a-3.5-1616-SUSE-SL10.3 without any problems, access to shares with dedicated group rights stopped working. Shares with user rights are still allright. New shares are working. Only those 2 weeks old, with all their groups not. Smbclient quits with: tree connect failed: NT_STATUS_BAD_NETWORK_NAME Smbd Log shows this: [2008/02/23 10:25:37, 3] lib/util_seaccess.c:se_access_check(251) se_access_check: user sid is S-1-5-21-1664890072-4027361542-1527094963-21002 se_access_check: also S-1-5-21-1664890072-4027361542-1527094963-21017 se_access_check: also S-1-1-0 se_access_check: also S-1-5-2 se_access_check: also S-1-5-11 se_access_check: also S-1-22-2-10008 [2008/02/23 10:25:37, 3] smbd/sec_ctx.c:set_sec_ctx(241) setting sec ctx (10001, 10008) - sec_ctx_stack_ndx = 0 [2008/02/23 10:25:37, 0] smbd/service.c:make_connection_snum(1003) '/home/groups/xxx_punkt' does not exist or permission denied when connecting to [treff] Error was Keine Berechtigung [2008/02/23 10:25:37, 3] smbd/sec_ctx.c:set_sec_ctx(241) setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0 [2008/02/23 10:25:37, 3] smbd/connection.c:yield_connection(69) This Share (xxx_punkt) is owned by group (Unix gid 10008) of connecting user (XXX), (XXX) User LDIF Entry shows the right sambaPrimeryGroupSid: 21017 So groupmapping ist working fine. G is: [global] workgroup = xxxx-F server string = Samba map to guest = Bad User passdb backend = ldapsam log level = 3 time server = Yes logon path = \\%L\profiles\.msprofile logon drive = P: logon home = \\%L\%U\.9xprofile domain logons = Yes os level = 99 preferred master = Yes domain master = Yes wins support = Yes ldap admin dn = cn=xxxxx,dc=xxxxx-f,dc=de ldap group suffix = ou=groups ldap machine suffix = ou=hosts ldap passwd sync = Yes ldap suffix = dc=xxxxx-f,dc=de ldap ssl = no ldap user suffix = ou=users winbind nested groups = No As you see the server is setted up as a PDC, at the moment his only role is to work standalone only for user and group shares. Surprising for me is the fact of 2 weeks working fine and stopping it without! changing anything. Regards Georg
