Thanks for bringing this up Sam.


I am reading the doc now and I have a question as to why we have a MUST
on the syntax of attributes like principalNotUsedBefore.

It says it MUST use "Internet Date/Time Format from [RFC3339]"

This is problematic as LDAP uses generalizedTime defined in RFC4517.
It is a representation of ISO8061 just like RFC3339, but a *different*
representation.

Trying to force all implementations to use the RFC3339 definition seem
wrong.
What implementation, today, uses RFC3339 ?

I would rather suggest that the document does not mandate the specific
representation discussed in RFC3339 but allow any ISO8601 based
representation.

If it is felt that one representation really needs to be chosen then I'd
ask to use the generalizedTime representation as defined by RFC4517
instead of the one in RFC3339.

Simo.
