When I do net groupmap add rid=514 ntgroup="Domain Guests" unixgroup=nobody type=d and then try to connect to a share called share which only allows guest connections with the following permissions: [global] guest account = nobody map to guest = bad user map to guest = bad password [share] path = /samba/admin force directory mode = 777 writeable = Yes create mode = 777 force create mode = 777 directory mode = 777 force group = admin guest ok = Yes guest only = Yes I get the error in the samba log: [2008/04/13 22:27:26, 2] passdb/pdb_ldap.c:init_group_from_ldap(2162) init_group_from_ldap: Entry found for group: 65534 [2008/04/13 22:27:26, 1] auth/auth_util.c:create_token_from_username(1110) nobody is a Domain Group, not a user however, if I run net groupmap delete ntgroup="Domain Guests" then I can connect to the share fine. Why is this? Why can't samba connect as the user nobody when the nobody group is mapped? nobody is loaded into ldap: [root@roark samba]# ldapsearch -D 'cn=Manager,dc=mdah,dc=state,dc=ms,dc=us' -b "uid=nobody,ou=People,dc=mdah,dc=state,dc=ms,dc=us" -w xxxxxxxxxxxx -x # extended LDIF # # LDAPv3 # base <uid=nobody,ou=People,dc=mdah,dc=state,dc=ms,dc=us> with scope subtree # filter: (objectclass=*) # requesting: ALL # # nobody, People, mdah.state.ms.us dn: uid=nobody,ou=People,dc=mdah,dc=state,dc=ms,dc=us uid: nobody cn: Nobody sn: Nobody mail: nobody@mdah.state.ms.us objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: posixAccount objectClass: top objectClass: shadowAccount objectClass: hostObject userPassword:: xxxxxxxxxxxxxxxx shadowLastChange: 13966 shadowMax: 99999 shadowWarning: 7 loginShell: /bin/sh uidNumber: 65534 gidNumber: 65534 host: roark host: archives3 host: arrowhead host: preshs host: wmounds host: manship host: welty homeDirectory: /home gecos: Nobody # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 [root@roark samba]# [root@roark samba]# ldapsearch -D 'cn=Manager,dc=mdah,dc=state,dc=ms,dc=us' -b "cn=nobody,ou=Group,dc=mdah,dc=state,dc=ms,dc=us" -w xxxxxxxxxx -x # extended LDIF # # LDAPv3 # base <cn=nobody,ou=Group,dc=mdah,dc=state,dc=ms,dc=us> with scope subtree # filter: (objectclass=*) # requesting: ALL # # nobody, Group, mdah.state.ms.us dn: cn=nobody,ou=Group,dc=mdah,dc=state,dc=ms,dc=us objectClass: posixGroup objectClass: top cn: nobody userPassword:: xxxxxxxxxxxxxx gidNumber: 65534 # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1
