No.  The resulting DN (whether its that produced automatically
or that produced through saslRegexp mapping) need not exist
in the directory.

 From GSSAPI authentication and access control perspective,
there is no need for users to have directory entries.  However,
entries for users are useful for other things...

For other mechanisms, it depends.

Since you using GSSAPI, whatever credential you provide
to get your Kerberos ticket is between you and your
KDC.  And OpenLDAP, itself, never sees the tickets.
That's left to Cyrus SASL.
