• DESCRIPTION
  
  
  sasl_canon_user_t Is the callback for an application-supplied user canonicalization function.

  functions are: It must copy the result into the output buffers, but the
  output buffers and the input buffers may be the same.
  
  context

  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.
