LDAP NAT Support

Hello All,

A customer has asked the question if ServiceNow LDAP configuration supports the use of NAT environments on their network.

I have found little information within the wiki to support this one way or the other.

Can anyone confirm or advise on the below question:

Does ServiceNow support access to Active Directory through a NAT-ed environment?

Additional information, the customer will be using an LDAPS setup.

Kind Regards

Alex Ward

Just to be clear, the NATs rules would be on your side, not SN side. Their is a note on 4.2 that mentions NAT but are setup is exactly that. For example, The IP address I enter into SN is behind our firewall, and NAT rules allow traffic from the 2 datacenters and routes it to connect to our AD LDAP Integration Setup - ServiceNow Wiki

Thank you for your reply Michael.


Just to be clear, in your set up the IP address used to access the Active Directory is the External or Internal facing IP address?


I am presuming this is the External IP Address?


Correct, external. It's available externally, but routes internally via NAT to your AD.


So if the external IP that is nating to my internal AD is 10.10.10.10 I should set the URL in the LDAP server record as ldaps://10.10.10.10:636/
