Well, that *sounds* like what I thought, but you sound as though you
disagree with me. So I'm still confused. Probably not enough vacation. :-)
I thought (a) you take your LDAP query and apply DN quoting. Then (b) you
apply URL quoting to that in order to include it in a URL. Here is an
extract from RFC 2255:
The next example illustrates the interaction between LDAP and URL
quoting mechanisms.
ldap://ldap.netscape.com/o=Babsco,c=US??(int=%5c00%5c00%5c00%5c04)
The filter in this example uses the LDAP escaping mechanism of \ to
encode three zero or null bytes in the value. In LDAP, the filter
would be written as (int=\00\00\00\04). Because the \ character must
be escaped in a URL, the \'s are escaped as %5c in the URL encoding.
That fits with the way I have always thought it should work.
There are certainly lots of sites using Exim with LDAP. Nobody has
previously raised this as an issue.

I don't know. I'd have to read the code, the LDAP manual, and think a
long time. It might be just as easy for you to do this. I am not an LDAP
person - most of the LDAP code has come from other people.

No, I'm afraid it is still on my "incoming" list. I have been away a lot
and am still busy (course coming up, book being rewritten). It is
unlikely that I'll get to it for a while. I want to get 4.05
(maintenance release) out as soon as I can, and then in a month or so
put out a 4.10 maintenance release with an updated manual. *Then* I
might get round to looking at substantial new stuff.
