SYNOPSIS

       #include <sasl/sasl.h>

       int sasl_canon_user_t(sasl_conn_t *conn,
                             void *context,
                         const char *user, unsigned ulen,
                             unsigned flags,
                             const char *user_realm,
                             char *out_user, unsigned out_umax,
                             unsigned *out_ulen)

DESCRIPTION

       sasl_canon_user_t  Is  the  callback  for  an  application-supplied user canonicalization function.  This
       function is subject to the requirements that all user canonicalization functions are: It  must  copy  the
       result into the output buffers, but the output buffers and the input buffers may be the same.

       context context from the callback record

       user and ulen Un-canonicalized username (and length)

       flags  Either SASL_CU_AUTHID (indicating the authentication ID is being canonicalized) or SASL_CU_AUTHZID
       (indicating the authorization ID is to be canonicalized) or a bitwise OR of the the two.

       user_realm Realm of authentication.

       out_user and out_umax and out_ulen The output buffer, max length, and actual length for the username.

RETURN VALUE

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