.SH SETUP USER AUTHENTICATION
If the server will handle user authentication through
monkeysphere-generated authorized_keys files, the server must be told
which keys will act as identity certifiers. This is done with the
-\fBadd-id-certifier\fP command:
+\fBadd\-id\-certifier\fP command:
-$ monkeysphere-authentication add-id-certifier KEYID
+# monkeysphere\-authentication add\-id\-certifier KEYID
where KEYID is the key ID of the server admin, or whoever's
certifications should be acceptable to the system for the purposes of
to indicate that multiple certifiers are trusted. You may also
specify a filename instead of a key ID, as long as the file contains a
single OpenPGP public key. Certifiers can be removed with the
-\fBremove-id-certifier\fP command, and listed with the
-\fBlist-id-certifiers\fP command.
