Sync AD Passwords across Domains
Hi,
We have two separate AD forests, each containing a single domain.
The "primary" forest and it's domain is our Company, the "secondary" forest and it's domain is of another company that we bough. They are now part of our Wide Area Network and need to access their own systems as well as some of our systems (one common intranet for the "group" etc.)
We have not setup a Domain Trust between us (for a few reasons) and as an alternative we have created their users (same usernames) on our Domain and would now like to find out if there's a way to sync their AD User passwords to the matching user on our side on our domain.
Example:
Their Domain is COMPANY2
Our Domain is COMPANY1
They had a User "COMPANY2\JoeSoap" with password "MySecretPassword"
We created a COMPANY1\JoeSoap with password "Password1"
The user can now use one login (JoeSoap) but he's got two passwords and because it being normal users they get confused when to use which password.
I now need to know how can I sync the password "MySecretPassword" back to COMPANY1\JoeSoap so that he also has this password (without asking each and every user for their password ofcourse...) Is there for instance any kind of LDAP tool or similar that can take a password from one user and sync to a matching username even thought it's on another domain and will have a differnet SID ?
Thanks a lot,
Reinhard

There is no good way to accomplish what you want. Although given the situation you laid out, a trust is exactly what you want. A domain trust isn't an open gate. You can still control and manage resources by security groups or other means. All a domain trust does is allow authentication of a claim to occur.

Dear Cliff,
Thanks a lot for your reply,
We had a chat to our service provider that supports our infrastructure and their exact words were:
In your opinion would you agree with this as being a short-term solution? I am unsure as to what "overhead" they are referring to, but as you stated a trust is merely allowing authentication of a claim to occur, and this seems to me is exactly what we need.
Thanks a lot,

It would be best to move everything into your domain as a long term measure. Creating a trust would be suitable and easy, but is very short term and can be quite an overhead from an operational and administration point of view.

Hi Cliff,
Thanks that makes sense, I think I now understand what they meant with "overhead", they mean that we would have to still separately manage their domain's Group Policies etc. which is fine as they have another Company looking after it in any way, and in time we can merge the domains.
Thanks, I think I've got my answer, there is not really any danger in doing a domain trust, as long as one is happy with managing Group Policies, integrated DNS etc. separately for that period of time (which will work for us).
Regards,
Reinhard
