I just moved from using samba 2.2.5 using ldapsam on a mac os x server 10.2.5 system to samba 3.0 alpha23. I have this samba server acting as a PDC. I would like to enable group mappings but am having an issue. This is the first group mapping error I get when a user first logs in: ldap_connect_system: succesful connection to the LDAP server [2003/04/19 13:39:00, 2] /Users/admin/newsamba/samba-3.0alpha23/source/passdb/p db_ldap.c:init_sam_from_ldap(1059) Entry found for user: sambauser [2003/04/19 13:39:00, 2] /Users/admin/newsamba/samba-3.0alpha23/source/passdb/p db_ldap.c:ldapsam_search_one_group(2187) ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gi dNumber=1002))] [2003/04/19 13:39:00, 2] /Users/admin/newsamba/samba-3.0alpha23/source/passdb/p db_ldap.c:ldapsam_search_one_group(2187) ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gi dNumber=-1))] [2003/04/19 13:39:00, 2] /Users/admin/newsamba/samba-3.0alpha23/source/passdb/p db_ldap.c:ldapsam_search_one_group(2187) ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber =-1))] [2003/04/19 13:39:00, 2] /Users/admin/newsamba/samba-3.0alpha23/source/passdb/p db_ldap.c:ldapsam_add_group_mapping_entry(2423) Group -1 must exist exactly once in LDAP I also get this error when running this command: sudo smbgroupedit -c "Domain Admins" -u domadmin (domadmin does exist as a group in ldap) ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(|(displayName=Domain Admins)(cn=Domain Admins)))] ldapsam_open_connection: connection opened ldap_connect_system: succesful connection to the LDAP server ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP ldapsam_search_one_group: searching for:[(&(objectClass=sambaGroupMapping)(gidNumber=-1))] ldapsam_search_one_group: searching for:[(&(objectClass=posixGroup)(gidNumber=-1))] Group -1 must exist exactly once in LDAP NT Group Domain Admins doesn't exist in mapping DB There actually DOES exist a group called "nogroup" that has an entry of gidNumber=-1. What am I doing wrong?
