I hope someone is able to assit.

We have installed the JBE on a CentOS Release 6.5 machine running Java 1.7.0_45.
Linux Distribution: CentOS Release 6.5 (Final)
Kernel Version:

Kernel Name: Linux
Kernel Version: 2.6.32-431.el6.i686

When running the JBE using a normal user account, the whole mechanism works correctly and no issues are encountered, in fact the builds are all working correctly.

However when we change the user for the JBE to use a dedicated build user (created on AD and has the same role (currectly) as the user where the JBE works) we get the following error message:

2015-01-13 08:15:58 [Jazz build engine] CRRTC3524W: Communication with the repository failed due to this error: CRJAZ1368E The following URL cannot be reached: https://{DNS-NAME}:443/ccm/versionCompatibility?clientVersion=5.0.
