I have two domains with an external trust between them. Verifying the trust from a domain1 controller using "samba-tool domain trust validate domain2 -U." returns "ERROR: Filed to find a writeable DC for domain 'DOMAIN2': The object name is not found." (See below.) However, the same command from a domain2 controller, "samba-tool domain trust validate domain1 -U.", does not get the error. Also, from the domain1 side, "samba-tool domain trust validate domain.domain2.com -U." works fine. How does samba-tool look up the short domain name? root at minister1:~# samba-tool domain trust validate brandlilaw -Uadministrator at domain.brandlilaw.com <mailto:-Uadministrator at domain.brandlilaw.com> LocalDomain Netbios[BRANDLI] DNS[domain.brandli.com] SID[S-1-5-21-3237397562-3087105784-2935402547] LocalTDO Netbios[BRANDLILAW] DNS[domain.brandlilaw.com] SID[S-1-5-21-2136821272-1111453333-1140905514] OK: LocalValidation: DC[\\temple2.domain.brandlilaw.com] CONNECTION[WERR_OK] TRUST[WERR_OK] VERIFY_STATUS_RETURNED OK: LocalRediscover: DC[\\temple2.domain.brandlilaw.com] CONNECTION[WERR_OK] ERROR: Failed to find a writeable DC for domain 'BRANDLILAW': The object name is not found. root at minister1:~# samba-tool domain trust validate domain.brandlilaw.com -Usteve at domain.brandli.com <mailto:-Usteve at domain.brandli.com> LocalDomain Netbios[BRANDLI] DNS[domain.brandli.com] SID[S-1-5-21-3237397562-3087105784-2935402547] LocalTDO Netbios[BRANDLILAW] DNS[domain.brandlilaw.com] SID[S-1-5-21-2136821272-1111453333-1140905514] OK: LocalValidation: DC[\\temple2.domain.brandlilaw.com] CONNECTION[WERR_OK] TRUST[WERR_OK] VERIFY_STATUS_RETURNED OK: LocalRediscover: DC[\\temple2.domain.brandlilaw.com] CONNECTION[WERR_OK] RemoteDC Netbios[TEMPLE2] DNS[temple2.domain.brandlilaw.com] ServerType[GC,LDAP,DS,KDC,TIMESERV,CLOSEST,WRITABLE,GOOD_TIMESERV,FULL_SECRE T_DOMAIN_6] Password for [steve at domain.brandli.com]: Password for [steve at domain.brandli.com]: OK: RemoteValidation: DC[\\bailiff1.domain.brandli.com] CONNECTION[WERR_OK] TRUST[WERR_OK] VERIFY_STATUS_RETURNED OK: RemoteRediscover: DC[\\bailiff1.domain.brandli.com] CONNECTION[WERR_OK] root at temple2:~# samba-tool domain trust validate brandli -Usteve at domain.brandli.com <mailto:-Usteve at domain.brandli.com> LocalDomain Netbios[BRANDLILAW] DNS[domain.brandlilaw.com] SID[S-1-5-21-2136821272-1111453333-1140905514] LocalTDO Netbios[BRANDLI] DNS[domain.brandli.com] SID[S-1-5-21-3237397562-3087105784-2935402547] OK: LocalValidation: DC[\\bailiff1.domain.brandli.com] CONNECTION[WERR_OK] TRUST[WERR_OK] VERIFY_STATUS_RETURNED OK: LocalRediscover: DC[\\bailiff1.domain.brandli.com] CONNECTION[WERR_OK] RemoteDC Netbios[BAILIFF2] DNS[bailiff2.domain.brandli.com] ServerType[GC,LDAP,DS,KDC,TIMESERV,CLOSEST,WRITABLE,GOOD_TIMESERV,FULL_SECRE T_DOMAIN_6] Password for [steve at domain.brandli.com]: OK: RemoteValidation: DC[\\temple2.domain.brandlilaw.com] CONNECTION[WERR_OK] TRUST[WERR_OK] VERIFY_STATUS_RETURNED OK: RemoteRediscover: DC[\\temple2.domain.brandlilaw.com] CONNECTION[WERR_OK] Any help would be greatly appreciated!
