Things like this won’t work… they fail with Invalid filter syntax  
filter = Net::LDAP::Filter.construct(“nisnetgrouptriple=(,user,)”)  
If I remove the parenthesis and it works fine.

or if you use  
filter = Net::LDAP::Filter.eq( “nisnetgrouptriple”, “(,user,)” )  
then that works fine…

but i want to have compound statements and take them from a web front  
end so this is all tedious to construct.

This will fail with invalid filter syntax as well:  
filter =  
Net::LDAP::Filter.construct("(&(objectClass=Person)(|(sn=Jensen)(cn=Babs  
J\*)))")

Anyone found better work arounds for things like this other than going  
to ruby/ldap c based gem?
