Access control configured using CAS. Project Matrix authorization strategy. After adding users in the table there are ERRORS.

The ajax call is this (firebug helped me):
http://###.###.###.####:8080/jenkins/jenkins/job/Empresi-Esb/descriptorByName/hudson.security.AuthorizationMatrixProperty/checkName?value=[WORKDOMAIN%2FuserName]

(replaced the IP,the domain and the username for security reasons).

It seems that the context name (jenkins) is repeated two times. I cannot understand how this link is builded by jenkins.
The issue is also in single job matrix configurations.

This issue seems to be linked to this other problem: http://jenkins.361315.n4.nabble.com/Validation-Problem-tp3226142p3226142.html
