Issue

A lot of authentication requests are sent to the Active Directory server from the OCI server. Logs look like bellow.

  • In ldap.log we can see a lot of errors, almost every second:

  • In sanscreen-client.log which is located on the /.../users/<username> directory of Windows, from which the OCI Java Client is accessing OCI, for the same timestamp:
