samba - May 2017 - Multiple Winbindd Instances and Disjoint AD domains

Hi ,

I need to use ntlm_auth across two different AD domains and their is no
trust between the 2 domains. I followed the post
http://samba-multiple-domains.blogspot.co.uk/2010/03/how-to-join-one-linux-box-to-two.html
<https://deref-mail.com/mail/client/44YIgEylY9w/dereferrer/?redirectUrl=http%3A%2F%2Fsamba-multiple-domains.blogspot.co.uk%2F2010%2F03%2Fhow-to-join-one-linux-box-to-two.html>


It seems like only 1 instance can own the Winbindd pipe and bringing up
additional instances causes the previous pipe to die.

I can use additional socket directory instructions in smb.confs for the
winbindd instances but then ntlm_auth doesnt know to locate the winbindd
pipe ?

The DNS infrastructure allows resolution of both domains and I can join to
both the domains.

Any pointers welcome.

Many Thanks
Arnab
