Description Heiko W. Rupp 2013-05-13 09:47:51 EDT
+++ This bug was initially created as a clone of Bug #961656 +++

The authentication in the REST api currently only supports local users, but no LDAP users.

We need to fix that.

--- Additional comment from Heiko W. Rupp on 2013-05-13 05:37:30 EDT ---

The simplest way to support LDAP would be to switch to the "RHQUserSecurityDomain", which fails as RHQ is removing / re-adding the domain on each start. 
EAP sees this and complains that the removal would leave the rhq-rest.war in an illegal state (with a referenced but not provided security-domain) -- see below

I currently see three possible options:
1) add the logic to add/remove LDAP support to the RHQRESTSecurityDomain
2) Fix the RHQUserSecurityDomain setup in the CustomJaasDeploymentService to
not touch the security-domain on each restart and to only add/remove the LDAP module when requested (and perhaps change flags on the other modules.
3) Check if the remove/re-add can be done in Transaction (A EAP-composite operation), so that other services only see the end result.

I think doing option 2) got just easier with the use of EAP6.1, as this now allows to individually address login modules:

[standalone@localhost:6999 authentication=classic] ./login-module=org.rhq.enterprise.server.core.jaas.

org.rhq.enterprise.server.core.jaas.JDBCLoginModule                 org.rhq.enterprise.server.core.jaas.JDBCPrincipalCheckLoginModule
[standalone@localhost:6999 authentication=classic] ./login-module=org.rhq.enterprise.server.core.jaas.LdapLoginModule:

add                          read-attribute               read-children-names          read-children-resources
read-children-types          read-operation-description   read-operation-names         read-resource

The REST api needs to authenticate users in exactly the same manner as CLI/UI
Comment 8 Heiko W. Rupp 2013-05-17 08:29:13 EDT
( as written in the linked BZ : master ba97ade9666a )
Comment 9 Mike Foley 2013-09-13 18:16:05 EDT
QE has automation running nightly with LDAP authentication and REST API.  This is working.
