Description Mark McLoughlin 2010-03-03 15:19:49 UTC

The AutoLogin command allows users on the same machine as the RHEV-M backend to avoid re-authenticating because RHEV-M can use the ServiceSecurityContext::WindowsIdentity property to check the calling user's identity.

No similar API exists in Java/JBoss, so this functionality has been disabled.

This thread on the mailing list discusses the need for the functionality and some ideas for how it might be implemented:

Comment 1 Itamar Heim 2010-03-24 20:13:08 UTC

Two issues here:
1. CLI (and maybe SDK) need to support implicit, persistent login in case of session failure[1].
2. CLI (and maybe SDK) need to support kerberos authentication for currently logged in windows/linux user

[1] pay attention the current implementation in 2.2 windows powershell is actually not correct. consider the following use case:
a. user is logged in to windows with domain\xxx
b. user opens powershell and runs a script which will login-user domain\yyy.
c. after several commands the session breaks, and implicit auto authentication will re-authenticate the user, but with the windows logged in user of domain\xxx, rather than the last user the user logged in with.

fixing #1 is relatively easy, since all we need to do is keep the login-user parameters and re-use them on session failure.
fixing #2 actually requires kerberos support from windows-->jboss-->AD (and later for linux-->jboss>AD/RHDS

Comment 2 Itamar Heim 2010-12-13 17:09:16 UTC

this is basically "support kerberos authentication" by backend

Comment 7 Juan Hernández 2014-06-16 13:40:35 UTC

Authentication is now external to the RESTAPI.

Comment 8 Alon Bar-Lev 2014-06-22 17:30:22 UTC

Working with mod_auth_kerb, implies that kerberos is enforced, no other method is enabled.
