[RADIATOR] check-items in chained authby queries

Michael,

Ok, I gave it a shot, and got some completely different results.  Thanks for the suggestion.  The order of check items is certainly taken into account, which I should have thought of.  However, the error I am receiving is a little strange.  All I have done is changed the order of the two check items.  Now I am getting an error that looks to be more of a Perl error than a Radiator error.

Here is the debug log:

If I cut-and-paste the query from the debug logs into a database query, it returns "group1" as the sole result, indicating that testuser is indeed a member.  However, it appears that Radiator does not agree.

Any further thoughts?  I appear to be getting closer to my goals, and appreciate your input.

Chuck

Never done this type of setup before, but maybe the 'Auth-Type=AuthHOTP' in the sql query should be after the 'GroupList="Group1 Group2 Group3"??  Again, not sure, but I would think the 'check' is done in order.  it sounds like you want to do the group list check first before checking the AuthHOTP. I don't see any config in the AuthHOTP section though.
