I am following the instructions in the Howto:Samba documentation on the FDS Wiki site. When I go to edit the Administrator account using the following command: pdbedit -U $( net getlocalsid | sed 's/SID for domain YOURWORKGROUP is: //' )-500 -u Administrator -r smbldap_search_domain_info: Searching for:[(&(objectClass=sambaDomain)(sambaDomainName=DOMAIN))] smbldap_open_connection: connection opened ldap_connect_system: succesful connection to the LDAP server smbldap_search_domain_info: Searching for:[(&(objectClass=sambaDomain)(sambaDomainName=DOMAIN))] smbldap_open_connection: connection opened ldap_connect_system: succesful connection to the LDAP server Username not found! I get the same "Username not found" error if I run "pdbedit -L -v -u Administrator" so it seems that the account doesn't exist, yet if run: ldapsearch -b dc=test,dc=com -x '(uid=Administrator)' # extended LDIF # # LDAPv3 # base <dc=test,dc=com> with scope subtree # filter: (uid=Administrator) # requesting: ALL # # Administrator, People, test.com dn: uid=Administrator,ou=People,dc=test,dc=com uid: Administrator cn: Samba Admin givenName: Samba sn: Admin mail: Administrator at test.com objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: posixAccount objectClass: top loginShell: /bin/bash uidNumber: 0 gidNumber: 0 homeDirectory: /root gecos: Samba Admin # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 Should this account have some Samba Domain info? What did I do wrong? Here is a copy of the sambaAdmin.ldif I used: dn: uid=Administrator,ou=People,dc=test,dc=com uid: Administrator cn: Samba Admin givenName: Samba sn: Admin mail: Administrator at test.com objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: posixAccount objectClass: top userPassword: {crypt}x loginShell: /bin/bash uidNumber: 0 gidNumber: 0 homeDirectory: /root gecos: Samba Admin And a copy of my smb.conf if it helps: [global] workgroup = DOMAIN security = user passdb backend = ldapsam:ldap://vandread.test.com ldap admin dn = cn=Directory Manager ldap suffix = dc=test,dc=com ldap user suffix = ou=People ldap machine suffix = ou=People ldap group suffix = ou=Groups log file = /var/log/samba/%m.log log level = 3 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 os level = 33 domain logons = yes domain master = yes local master = yes preferred master = yes wins support = yes logon home = \\%L\%u\profiles logon path = \\%L\profiles\%u logon drive = H: template shell = /bin/false winbind use default domain = no winbind nested groups = no enable privileges = yes Thanks.
