Hi,
RFC 3325 states that a proxy may use the P-Preferred-Identity in
an incoming request as a hint to choose among multiple identities that
are configured for a user. The example section shows an example where
the user suggets that he prefers to use the identity [EMAIL PROTECTED] But
the proxy inserts [EMAIL PROTECTED] in the forwarded request.
The RFC does not clearly specify how the proxy should interpret
the 'hint' that is provided. From the syntax of the P-Preferred-Identity
and
the P-Asserted-Identity it seems that one should do a URL comparison to
choose the correct PAI header. But from the example, it seems like either
the display-name or the userinfo part is being used to choose the correct
PAI header.
Can someone provide some clarity or point to discussions which
indicate how the 'hint' should be interpreted. Is it that no rules have
been
laid down so that it is left to individual implementations ? In that case,
could
implementors/authors suggest as to how one would normally interpret the
hint i.e. by comparing which part of the P-Preferred-Identity header.
Thanks in advance,
