Hi Mike, I've just tried one more time to reproduce your error and I failed again. With your config file the behavior is the absolutely the same for both cases with my patchset and without my patchset: * for dynamic ACLs - target fails the login and shows the bellow logs. * for the registered ACL - target succeeds the login. Could you, please, re-check the patchset?

This kind of error is reported for the unknown (dynamic) ACL since the config file have not have userid/password configured for TPG. Your config file looks strange - it has generate_dyn_acls=1 but has not credentials for dynamic acls. Login from the configured ACL in this config file works well for me. Could you, please, describe more details of your usecase? BR, Dmitry
