NAME
       sasl_setprop - Set a SASL property
SYNOPSIS
       #include <sasl/sasl.h>
       int sasl_setprop(sasl_conn_t *conn,
                       int propnum,
                       const void * pvalue)
DESCRIPTION
       sasl_setprop  sets  the  value  of  a  SASL  property.  For  example an
       application should tell the SASL library about any external  negotiated
       security layer (i.e. TLS).
       conn  is the SASL connection object.  propnum is the identifier for the
       property requested and pvalue contains a pointer to the data. It is the
       applications job to make sure this type is correct. This is an easy way
       to crash a program.
       SASL_AUTH_EXTERNAL - external authentication ID (const char *)
       SASL_SSF_EXTERNAL -  external SSF active -- (sasl_ssf_t)
       SASL_DEFUSERREALM - user realm (const char *)
       SASL_SEC_PROPS  -    sasl_security_properties_t (may be freed after call)
       SASL_IPLOCALPORT -   string describing the local ip and port in the form
                            "a.b.c.d;p", or "e:f:g:h:i:j:k:l;port"
       SASL_IPREMOTEPORT -  string describing the remote ip and port in the form
                            "a.b.c.d;p", or "e:f:g:h:i:j:k:l;port"
RETURN VALUE
       Returns SASL_OK on success. SASL error code on failure.
