They may be used in any context, and are kept relatively -simplier enought to let you customize them to you needs. - -They need the following objectClasses to work: - . sambaAccount: from samba.schema for Samba 2.2 branch - . posixAccount and posixGroup : from nis.schema - . organizationalUnit and dcObject: from core.schema - -They will probably use in a near future some additional objectClasses -to support : - . mail features (sendmail/postfix/qmail/courier). - . conform to RFC2307 best practices (and so some maps too like merging - Netbios computers (sambaAccounts) with ipHosts - -For ease of visualization of the LDAP objects by human standards, we -used a DIT like this one : - . dc=IDEALX,dc=org : the company/organization suffix - . ou=Users : to store users accounts - . ou=Computers : to store computers accounts - . ou=Groups : to store system groups -Of course, you're free to use a different naming scheme and DIT (see -smbldap_conf.pm). - - -Built in groups initial population -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= - -smbldap-populate.pl populate the LDAP directory with some built in groups -using gidNumber according to Well Know RID of Windows NT4 Srv. In fact, As -far a Samba 2.2.x is concerned, only the 'Domain Admins' (gidNumber 512) have -real inpact on the Samba and Windows population. To activate this group as -the Domain Administrators Group, use the following smb.conf directive (see -man smb.conf for more): - - domain admin group = " @"Domain Admins" " - -However, to make pdb_ldap accept bind without being uid=0, a quick and -dirty patch must be applied to 2.2.4 (see samba-2.2.4-ldapbindnotuid0.patch). -This patch is Q&D because the check is there because Samba store admin -credentials to establish the LDAP connection. The uid == 0 check was to -ensure that a normal user could not get write access to the LDAP backend. -A more logical situation should be done for 2.2.5 by checking if the user -is a member of the domain admin group (reported to Jerremy and Gerald -2002-05-28). - -Other built in groups are really cosmetic ones with Samba 2.2.x. We did not -removed them because one of these days, we whish to use Samba 3.0 where -Windows Group Support should be operational. - -Why these specific gidNumbers ? -It's about unix/windows mapping of numerical ids with Samba. Ids below 1024 -are NT special ids. In fact, 512 is the RID (Windows uid/gid) for the -"Domain Administrators" NT group. The magic number is found in Samba sources -and possibly other Samba/Windows documentations. - -The goal is to have a set of Unix users who are Domain Administrators and can -modify Samba datas (eg. LDAP content), with commandline tools or within -Windows via Samba. - -Say you want to add a NT4 ws to an NT domain (controlled by a samba/ldap -server). You give the domain administrator's login and password in the -appropriate ws settings, then the ws contacts the samba server, which checks -the credentials and use them as unix user to run the smbldap-tools (if I -remember). Giving 512 as a RID to a LDAP entry marks it as a domain admin -for Samba (thus Windows). Using nss_ldap, you also have an account with -gid 512. - - -Known BUGS and WORKAROUND used -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= - -The 2.2.2 has at least a bug : rid/primaryGroupID are read as hex in LDAP, -but written as decimal. Fixed in CVS by reading as decimal. By default -smbldap-useradd.pl writes decimal to LDAP. Use -x to support the odd -behaviour. - -The samba-2.2.4-ldapbindnotuid0.patch is not a perfect solution however -as the check is there because Samba store admin credentials to establish the -LDAP connection. The uid == 0 check was to ensure that a normal user could -not get write access to the LDAP backend. A more logical situation should be -done for 2.2.5 by checking if the user is a member of the domain admin group -(reported to Jerremy and Gerald 2002-05-28). - -# - The End |
