I have already posted another issue here<http://samba.2283325.n4.nabble.com/Samba4-Problem-with-Joining-Samba3-to-Samba4-AD-Domain-td4642466.html>that may be related the current issue I am having. I have Three Samba4 AD Domain Controllers, the first one installed that was the primary domain controller is the one having problem, the other two seem to be working OK. I discovered the problem when I tried to set "Group Policy" from windows 7 machine. The Current issue and the previous issue that I have posted<http://samba.2283325.n4.nabble.com/Samba4-Problem-with-Joining-Samba3-to-Samba4-AD-Domain-td4642466.html>all started after I tried to add active directory Service to FreeNAS 8.0.3. When i run the "Group Policy Management Console" (gpmc.msc) I get the error message: " The domain.company.com forest could not be loaded and will be removed. The error message was: Unspecified Error". I stopped Samba and run it in single mode: [root at SAMBA-AD ~]# /usr/local/samba/sbin/samba -i -M single and then run gpmc.msc and the got the following message: Failed to bind to uuid e3514235-4b06-11d1-ab04-00c04fc2dcd2 for e3514235-4b06-11d1-ab04-00c04fc2dcd2 at ncacn_ip_tcp :14c15c29-7c8e-4b7a-8e5a-639da645e970._msdcs.domain.company.com[1024,seal,krb5] NT_STATUS_LOGON_FAILURE Here are are a list of commands that I ran and the results that I got, I hope they provide a clue of what might be going on: [root at SAMBA-AD ~]# wbinfo -u Error looking up domain users [root at SAMBA-AD ~]# wbinfo -g failed to call wbcListGroups: WBC_ERR_DOMAIN_NOT_FOUND Error looking up domain groups [root at SAMBA-AD var]# wbinfo -i vavanessians failed to call wbcGetpwnam: WBC_ERR_DOMAIN_NOT_FOUND Could not get info for user vavanessians [root at SAMBA-AD var]# smbtree -U Administrator -D Enter Administrator's password: WORKGROUP SYS_OPS SUNBELT SHEETMETAL SERVICE SERIVCE PURCHASING PROJET_GROUP PROJECT_GROUP PROJECT PRODUCTION PIPING PAYROLL MSHOME IT HR ENG DISPATCH CONST BILLING AESNB ADMIN ACCOUNTING DOMAIN [root at SAMBA-AD var]# wbinfo --domain=DOMAIN [root at SAMBA-AD var]# wbinfo -t checking the trust secret for domain DOMAIN via RPC calls failed error code was NT_STATUS_NO_TRUST_SAM_ACCOUNT (0xc000018b) failed to call wbcCheckTrustCredentials: WBC_ERR_AUTH_ERROR Could not check secret [root at SAMBA-AD var]# [root at SAMBA-AD ~]# smbclient -L SAMBA-AD -U Administrator Enter Administrator's password: Domain=[DOMAIN] OS=[Unix] Server=[Samba 4.1.0pre1-GIT-229d934] Sharename Type Comment --------- ---- ------- netlogon Disk sysvol Disk Data Disk IT Disk IPC$ IPC IPC Service (Samba 4.1.0pre1-GIT-229d934) Domain=[DOMAIN] OS=[Unix] Server=[Samba 4.1.0pre1-GIT-229d934] Server Comment --------- ------- Workgroup Master --------- ------- [root at SAMBA-AD ~]# samba-tool fsmo show InfrastructureMasterRole owner: CN=NTDS Settings,CN=SAMBA-AD,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=DOMAIN,DC=COMPANY,DC=com RidAllocationMasterRole owner: CN=NTDS Settings,CN=SAMBA-AD,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=DOMAIN,DC=COMPANY,DC=com PdcEmulationMasterRole owner: CN=NTDS Settings,CN=SAMBA-AD,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=DOMAIN,DC=COMPANY,DC=com DomainNamingMasterRole owner: CN=NTDS Settings,CN=SAMBA-AD,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=DOMAIN,DC=COMPANY,DC=com SchemaMasterRole owner: CN=NTDS Settings,CN=SAMBA-AD,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=DOMAIN,DC=COMPANY,DC=com [root at SAMBA-AD ~]# Thanks in advance for any help that you can provide.
