Hello,
I've just submitted a patch to help make the collect overlay (attribute inheritance) a bit more useful (ITS#5659).
As part of my testing work for the above i once accidentally created a postalAddress attribute with two values. When i tried to remove the extra attribute value it failed, the error i got was something like that there is no matching rule for postalAddress, which if there really isn't then it's probably a reasonable thing for slapd to complain about, as it wont be able to tell the individual values of postalAddress apart.
So to put it in a nutshell, i'm willing to have a go implementing a postalAddress matching rule, but i was wondering if anyone has any thoughts where i might begin, and/or any pointers as to which file(s) implement the matching rules.
Cheers Brett
