Subject: [PATCH 103/104] Move sized_output_name() and sized_domain_name() into
responder common code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
These functions are used to format a name into a format that the user
configured for output, including case sensitiveness, replacing
whitespace and qualified format. They were used only in the NSS
responder, which typically returns strings to the NSS client library and
then the user.
But it makes sense to just reuse the same code in the IFP responder as
well, since it does essentially the same job.
The patch also renames sized_member_name to sized_domain_name.
Previously, the function was only used to format a group member, the IFP
responder would use the same function to format a group the user is a
member of.
