Howard Chu writes: Ah, OK. Sounds worthy of an ITS though. And it makes the rest of my last message a different issue: Something like this - except I've likely forgotten enough Perl to get it quite right: back-perl creates a Perl module back_perl. Possibly foo.pm inherits from it. foo.pm calls back_perl::new() which creates an ordinary new slapd backend. It looks up foo::<search, add...> and creates bi_op_<search, add, ...> for the Perl functions that foo defines. It does not set e.g. bi_op_add if perl method foo::add does not exist. Somehow foo.pm must be loaded, and we'll never say 'database perl' so we can't do it there - but we can do it under 'backend perl'. -- Hallvard
