Start at hudson.plugins.active_directory.ActiveDirectorySecurityRealm$DescriptorImpl.bind, the entry point named in the stack trace, and trace how username validity is tested with Matrix Authorization Strategy. Reproduce the failure against the reported Jenkins 2.387.1 setup; done means username validity can be tested across the security matrices without the reported connection-reset error.
