Hi All,

OpenLDAP version : 2.4.39 on windows

Tool used : Microsoft Attack surface analyzer

We have been doing attack surface analysis on OpenLDAP server, and we have found that there is an UDP port 63515 associated with OpenLDAP server. (state shows "Unknown", not listening or established)

We have not connected any clients to OpenLDAP server, so we cannot think of it as an ephemeral port at server end as well.

Has anyone an idea on what this port could be for. Inputs are much appreciated.
