UA 4.01 Build Revision 37294 on SLES in JBoss.

I have a value in x500UniqueIdentifier in eDir, that is a Octet Stream
syntax attribute holding a GUID like attribute.

I define it in the DAL on a user, it is populated, (iMan shows the HEx
on one side, the GUID format on the other). But when I try to read it
in a workflow with:

IDVault.get(recipient, 'user', 'x500uniqueIdentifier');

I get an error: Failed to evaluate.

I assume this is a syntax issue?

I tried defining it in the DAL as string and as Stream. No joys there.

Any thoughts?
