Version 5.3.0

- Timestamps in authproxy.log output now show milliseconds. - The authproxy_passwd tool now preserves comments when encrypting all passwords and secrets in the authproxy.cfg file with the --whole-config option. - When security_group_dn is defined in an ad_client section, the connectivity tool confirms that an LDAP search for the group distinguished name returns a result. - Fixes the connectivity tool's error detection for mismatched TLS certificate keypairs. - When upgrading an existing install, the Authentication Proxy installer runs the connectivity tool to validate your configuration for correctness.
