Hi Michael,
Thanks for your reply.
And are you and the developers of this LDAP client aware that originally this attribute was meant to carry a signed S/MIME message with empty body to also carry the S/MIME capabilities of a client?
Yes, we are aware of that, and that's how we've implemented our software.
But I wasn't aware of this:
[...] After that I never saw a client making correct use of this attribute.
I was speaking of MS Outlook, but now I've performed a few more tests with Thunderbird and Apple Mail, and neither of them did accept the format. Not sure if they did not accept the LDAP attribute or didn't know how to make use of it, but I admit I'm baffled.
Can it be true that this attribute was never ever implemented properly in any of the (widely used) email clients? How disappointing!
Now I understand why my request was rejected. There is nothing that could be reasonably compatible.
Thanks Metin
