mentalray for maya on centos

Hi There,

We are running into problems trying to get the licensing working with the mayatomr on out centos render nodes.

running : /usr/autodesk/maya2014-x64/bin/Render -r mr -s 1 -e 1 -b 1 -v 6 /tmp/test/ball_mr.ma

errors with:

maya: License was not obtained

License method:
environment variable MAYA_LICENSE_METHOD='network'

Product choice:
environment variable MAYA_LICENSE='657e1'

License file override:
environment variable MAYA_ALT_EN is not set

I know that mayabatch mode and maya software renderer work correctly, but when we try to render with mentalray it fails.

we are running maya2014 sp3, on CentOS release 6.5 (Final)

I know that the "/var/opt/Autodesk/Adlm/Maya2014/MayaConfig.pit" was created correctly from our licensing info.

Please let me know if there is anymore information i can provide.

Cheers

Kym
