Behavior of LDAP LISTENER

[Community Alums]

Hi All,

I am just curious to know more about LDAP Listener behavior. 

I have gone through the community doc: https://docs.servicenow.com/bundle/tokyo-platform-security/page/integrate/ldap/task/t_EnableAListene...

which says, whenever there is a change in the AD User/Group, automatically it will pass the information into ServiceNow to update the records.

Here my questions are:

1. How Listener will identify which records got updated recently? or is this going to do a full scan of the LDAP?

2. In servicenow, is this going to update only recently modified records? or it will run the full data load?

Please let me know how it works in ServiceNow.

Thank You in advance.

Regards,

Ganesh

Hi @Community Alums ,

Check this article:

https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0961314

The LDAP listener is used to look for changes(event based) in AD and re import those objects in Servicenow(keeping data in sync with AD realtime). It cannot send requests from Servicenow.

1. LDAP listener is our version of a persistent query (or persistent search). We issue a standing query for changes made to your LDAP server, and constantly listen for a response. Assuming your server supports a persistent search, any changes made to any of your applicable LDAP accounts are returned to the LDAP listener and sent to your instance within approximately 10 seconds. This is an extremely useful tool, allowing us to have a nearly real-time copy of your users' account details, without having to wait for the next scheduled refresh.

Hello @reshmapatil : Thank you for your reply. I have few more confusions regarding the same.

1. Our LDAP Server is using persistent search. Is this going to do full query or only it will query the records which have latest changes to it?

2. How Ldap Listener is going to useful in this case.

Thanks in advance.
