[midPoint] Warnings LdapNetworkConnection: Connection reset

[João Paulo Ribeiro]

Hello!

I am using the AdLdapConnector to connect to an Active Directory. I notice
that after ~15 minutes the following exception is thrown in the logs:

I found an issue on Evolveum's OpenProject about this:
https://support.evolveum.com/projects/midpoint/work_packages/3588.

Is there any way to avoid these exceptions? A timeout that I can set in the
connector configuration to resolve this?

Thanks in advance!

João Paulo Ribeiro.
