Should Backup Exec 9 be able to see and backup OES Linux based NSS volumes?

We have configured the OES Linux servers TSAFS to show the NetWare file

/opt/novell/sms/bin/smsconfig -l tsafs --tsaMode=dual

The server and file systems are visible using SBCON

However, despite specifying the 'agent' settings in BE (effectively the
NDMPSVRS.DAT file) with the name and IP of the oeslx box it won't show....

The 9.2 product sheet seems to say it should...

Any thoughts? (and please don't suggest syncsort - haven't go the cash or
the patience! ;-)
