sasl_setprop - Set a SASL property

Synopsis

#include <sasl/sasl.h>

int sasl_setprop(sasl_conn_t *conn,
                int propnum,
                const void * pvalue)

Description

int sasl_setprop(sasl_conn_t *conn,
int propnum,
const void * pvalue)

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).

Parameters:
  • conn – is the SASL connection context
  • propnum – is the identifier for the property requested
  • 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

SASL callback functions should return SASL return codes. See sasl.h for a complete list. SASL_OK indicates success.

Other return codes indicate errors and should be handled.
