index_param failed

[Curt Blank <curt@uwm.edu>]

I'm getting these:

<= bdb_equality_candidates: (uwmXythosUser) index_param failed (18)

and I saw Quanah say this is because the attribute, in my case 
uwmXythosUser, is not indexed. In this case that is true, uwmXythosUser 
is not indexed. It can be "Y", "N", or not exist and it is used in ACL 
filters to allow access to an application. I didn't think indexing it 
would pay off since if it exists 99% of the time it's going to be "Y". 
So/But should I index it to get rid of the error message? And/Or is not 
having it indexed detrimental to the DB and/or LDAP.
