I have two domains, in a trusted relationship, that I'm trying to manage from a C# web application. To do that, I have to impersonate two different technical users, but that works good, so I will not emphasize that part of the code.
To build proper and easy to manage ACLs for the file system, I must
- Create a group in domainA (OK!)
- Find a user in domainB (OK!)
- Add the user to the group (FAILS when committing changes, error message:
There is no such object on the server. (Exception from HRESULT: 0x80072030)
)
If I'm adding a user from the same domain, the code works perfectly, so I believe I'm only missing a small partial info here. I used this document as a reference and saw this question as well (and a few more citing this error message) but neither of them helped.
Code (try-catch block removed to make it simpler)
// de is a DirectoryEntry object of the AD group, received by the method as a parameter
// first impersonation to search in domainB
// works all right
if (impersonator.impersonateUser("techUser1", "domainB", "pass")) {
DirectoryEntry dom = new DirectoryEntry("LDAP://domainB.company.com/OU=MyOU,DC=domainB,DC=company,DC=com", "techUser1", "pass");
de.Invoke("Add", new object[] { "LDAP://domainB.company.com/CN=theUserIWantToAdd,OU=MyOU,DC=domainB,DC=company,DC=com" });
// de.Invoke("Add", new object[] { "LDAP://domainA.company.com/CN=anotherUserFromDomainA,OU=AnotherOU,DC=domainB,DC=company,DC=com" });
impersonator.undoImpersonation();
}
// second impersonation because the group (de) is in domainA
// and techUser2 has account operator privileges there
if (impersonator.impersonateUser("techUser2", "domainA", "pass"))
{
de.CommitChanges();
impersonator.undoImpersonation();
return true;
}
else
{
// second impersonation was unsuccessful, so return an empty object
return false;
}
Line 6 works, if I debug it or force the properties to be written to HttpResponse, it is clearly there. So the LDAP queries seem to be OK.
Also, if I comment out line 6 and uncomment 7, so basically I add a user from the same domain, the whole thing works miraculously. With domainB, I'm stuck. Any good piece of advice?
