Could not authenticate with the NetWorker server as NMSAP HANA.

Anyone backing up SAP HANA using NMSAP? :-)  If yes, I would appreciate your input on this one above.  I use NMSAP 8.2SP1 on HANA side, but backup seems to fails for what can be seen as following in backint raw log:

0 03/24/15 13:52:41  5 3 13 1 8913010 0 nsrd RAP critical Permission denied

70922 03/24/15 13:52:41  3 5 0 1697912576 53362 0 hdbbackint NSR error Backint exiting at with fatal error: Could not authenticate with the NetWorker server as NMSAP HANA.

This is a bit strange and at the first look I would say quite obvious as it seems like some sort of impersonation takes place or index access and there is no right access rights.  I already had:

user=*,host=$HANA_hostname

user=*,host=$HANA_FQDN

... on DB admin and operator list, but that didn't help.  Then I added those to super admin list - but still no luck.  Licenses are not an issue (unless there is special SAP HANA backup license, but I'm not aware of that).
