Can't join as DC on Samba4 Beta4/5

[Srinath Mantripragada]

Works fine for member:


root at samba4-2:/usr/local/src/samba-master# samba-tool domain join int.oinkdigital.com MEMBER -U administrator --realm=int.oinkdigital.com
Password for [WORKGROUP\administrator]:
Joined domain ONK (S-1-5-21-4049503596-2436987728-3178021839)


Fails with WERR_DS_INTERNAL_FAILURE with DC:


root at samba4-2:/usr/local/src/samba-master# samba-tool domain join int.oinkdigital.com DC -U administrator --realm=int.oinkdigital.com
Finding a writeable DC for domain 'int.oinkdigital.com'
Found DC samba4-1.int.oinkdigital.com
Password for [WORKGROUP\administrator]:
