Incorrect UPN's and Active Directory

Hi Experts!

      One thing that is constantly causing issues for us is accounts in AD that have incorrect UPNs.  By incorrect, I mean the suffix is not @abc.com, but rather @test.abc.com.  If the UPN of the AD account is not always employeeID@abc.com, lots of stuff breaks, like IWA, password sync, user attribute import/export.  Is it possible to run something that enumerates the UPN for all users and dump the ones that don't have the correct suffix?  This way, I can get the output list that this script generates and contact those folks that are creating accounts incorrectly.  Any help with this  would be greatly appreciated.  Thanks.

Sure, that's not too tricky.

This vbscript will drop them to a tab delimited text file. Should be easy enough to drop that into Excel or similar if required. It will have columns for the distinguishedName, name and current UPN.

The Filter at the top says which it will find, not that it's currently looking for those with *@test.abc.com.

strFilter = "(userPrincipalName=*@test.abc.com)"
strFields = "distinguishedName,name,userPrincipalName"
 
Set objFileSystem = CreateObject("Scripting.FileSystemObject")
Set objFile = objFileSystem.OpenTextFile("IncorrectUPN.txt", 2, True, 0)
 
objFile.WriteLine Replace(strFields, ",", VbTab)
 
Set objConnection = CreateObject("ADODB.Connection")
objConnection.Provider = "ADsDSOObject"
objConnection.Open "Active Directory Provider"
 
Set objRootDSE = GetObject("LDAP://RootDSE")
Set objRecordSet = objConnection.Execute( _
  "<LDAP://" & objRootDSE.Get("defaultNamingContext") & ">;" & _
  strFilter & ";" & strFields & ";subtree")
Set objRootDSE = Nothing
 
Dim arrLine()
 
While Not objRecordSet.EOF
  arrFields = Split(strFields, ",")
 
  ReDim arrLine(0)
  For i = 0 to UBound(arrFields)
    ReDim Preserve arrLine(i) : arrLine(i) = ""
    arrLine(i) = objRecordSet.Fields(arrFields(i)).Value
  Next
 
  objFile.WriteLine Join(arrLine, VbTab)
 
  objRecordSet.MoveNext
WEnd

I should have noted that I posted VbScript because of the zones it was posted, but you can do the same thing through anything that can use the LDAP Filter (AD Users and Computers, DSQuery, ADFind, etc, etc).

This is the important part:

(userPrincipalName=*@test.abc.com)

That's used to find the results, everything else is just a wrapper to make it do it and write the results out.

There's only one other modification I can think might be useful. If you wanted this to search an entire forest you would modify this line:

  "<LDAP://" & objRootDSE.Get("defaultNamingContext") & ">;" & _

Changing it to:

  "<GC://" & objRootDSE.Get("rootDomainNamingContext") & ">;" & _

Although it falls apart a bit if you have a disjointed namespace.
