Login via VO uses too many grace logins

Hi,

When a user with an expired password logs in via VO/web browser 4 grace
logins are used rather than the 1 used by the ordinary client. This means
that if the initial grace logins are set to the normal value of 6 a user
only needs to decline to change their password TWICE for all the grace
logins to be used.

TID 10088930 mentions something like this but it's for iFolder 2.0 on NW 6.0
and says that for iFolder 2.1 on NW 6.5 you will need another patch and then
refers you to itself! No mention of what this 'other patch' might be.

Any ideas?

Thanks,

Tim.
