[ANN] LDAP plugin 1.15 has validation button

[Stephen Connolly]

We have added a "Test LDAP settings" button to the LDAP plugin in version 1.15

I strongly recommend that you use this button to validate your existing configuration.

I have seen cases where the LDAP settings contained incorrect configuration for either user lookup or group resolution. These issues can be subtle - typically only seen by users during API token access over the REST API or when using the Jenkins CLI with SSH Key based authentication... and often dismissed by the users.

The wise Jenkins administrators will be testing the LDAP plugin update in a test Jenkins prior to upgrading (you can still leverage the test button to check your configuration this way as long as you replicate the LDAP config from your production Jenkins into the test Jenkins)

See JENKINS-43388 for more details on this new feature
