LDAP query can't run from Intune enrolled client

Question

Hi

For several years I have had VBA code running in Outlook clients. Some of the code makes LDAP queries.

I have had a traditionally AD/DC setup which right now is hybrid. If the LDAP query is initiated from a computer registrered in our AD the query will run perfectly and give me correct answers. When the query is initiated from a computer enrolled in Intune (and thereby not listed in AD) the query can't run. The error is:

"The specified domain either does not exist or could not be contacted"

The 2 computers are on the same LAN and having same DNS settings and query is made from an Outlook client where the same user is logged in.

With regard to the 2 compuer's environment variables they share domain values.

How come the query can't run from the Intune enrolled computer?

Answer 1

@Allan Reese, Thanks for posting in Q&A. For the Intune enrolled device, is it Microsoft Entra joined device or a Microsoft Entra hybrid joined device?

If it is a Microsoft Entra joined device, it is not joined AD domain and it is unable to do LDAP query due to authentication issue.

Please check the above information and if there's any update, feel free to let us know.
