The authentication identity can be in any form.  I rather the
form be as "natural" as possible.  That is, if the authentication
identity is derived from an X.509 certificate, the identity
should be "natural" (e.g. X.500) form.

Once you have identity and associate session security
factor, you just need to let SASL know about it.  The
code is already prepped for the call:
#if 0       
            /* we need to let SASL know */
            slap_sasl_external( c, ssf, authid );

ssf should be specified as well:
/* security layer strength factor -- an unsigned integer usable by the caller
 *  to specify approximate security layer strength desired.  Roughly
 *  correlated to effective key length for encryption.
 * 0   = no protection
 * 1   = integrity protection only
 * 40  = 40-bit DES or 40-bit RC2/RC4 
 * 56  = DES
 * 112 = triple-DES
 * 128 = 128-bit RC2/RC4/BLOWFISH
