cifs-utils: Create new binary cifs.idmap for sid to uid/gid mapping (try #4)
Handle cifs.idmap type of key. Extract a SID string from the description
and map it to either an uid or gid using winbind APIs.
If that fails (e.g. because winbind is not installed/running or winbind
returns an error), kernel assigns uid and gid (from mount superblock).
Enable including winbind header files and idmapping code conditional
to winbind devel rpms (header and library).
An entry such as this
create cifs.idmap * * /usr/sbin/cifs.idmap %k
is needed in the file /etc/request-key.conf.
[Note: Modified to not build new tool by default, and to fix up some
whitespace munging]
