SASL_CANON_USER_T(3) Cyrus SASL SASL_CANON_USER_T(3)

NAME

sasl_canon_user_t - Cyrus SASL documentation

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 – un-canonicalized username
  • ulen – length of user
  • 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 – The output buffer for the canonicalized username
  • out_umax – Maximum length for out_user
  • out_ulen – Actual length of out_user

SASL_OK indicates success. See sasl_errors(3) for a full list of SASL error codes.
