OK, I tried TDE in openSUSE 13.2. In 13.2 I can not mount other 
volumes,
TDE gives error message:


Unable to mount this device.
Potential reasons include:
Improper device and/or user privilege level
Corrupt data on storage device

Technical details:
org.freedesktop.UDisks2.Error.NotAuthorizedCanObtain: Not authorized to 
perform operation


There is a difference between 13.2 and Leap 42.2.

What program does TDE use for mounting volumes? I would like to know 
where to
search for the differences.

Thanks,
