Multivalued attributes are already handled by ldap, and so there's no
need for a field separator within the value at all - *that* was the
problem with the original implementation.  It worked just fine in 1.0.x,
you could read/write them (using the deprecated "categories" ldap
attribute), but you couldn't search using them.

The 1.0.x version would store it like:

categories:  Business,Birthday,...

so any ldap search over categories would have necessarily been lossy.. 
we'd have to use "*Business*" as the filter, which is clearly broken.

The new way is:

category:  Business
category:  Birthday

which is much better.

I just brought up the contact editor here and the category button and
text field aren't even sensitive, which is undoubtedly caused by a typo
I just found in pas-backend-ldap.c.

I've attached a patch that I'll be sending to the patches list tomorrow,
but for now I'm exhausted and going to bed.

I'm confused by this - does the calCalURI/calFBURL stuff not work the
way evo uses it?  There's not a bug (to my knowledge) filed against it.

o SSL/TLS:  works
o correct adherence to directory trees:  you'll need to define that
better, not sure what more we can be doing given the the contact
editor/manager scope we have to operate in.
o categories: with the attached patch they should work - they should
have been before, can't believe I missed that... (Let me know if they
don't, Bill).
