# sasl_auxprop_request - Request auxiliary properties from SASL

## Synopsis

    #include <sasl/sasl.h>

    int sasl_auxprop_request(sasl_conn_t *conn, const char ** propnames)

## Description

int sasl_auxprop_request(sasl_conn_t *conn, const char **propnames)

  sasl_auxprop_request will request that the SASL library obtain properties from any auxiliary property plugins that might be installed (such as the user’s home directory from an LDAP server for example). Such lookup occurs just after username canonicalization is complete. Therefore, the request should be made before the call to sasl_server_start(3), but after the call to sasl_server_new(3).

  Parameters:

    - conn – the `sasl_conn_t` for which the request is being made.

    - propnames – a NULL-terminated array of property names to request. Note that this array must persist until a call to sasl_dispose(3) on the `sasl_conn_t`.

  Returns:

    Returns `SASL_OK` on success. See sasl_errors(3) for meanings of other return codes.
