# sasl_checkpass - Check a plaintext password

## Synopsis

    #include <sasl/sasl.h>

    int sasl_checkpass(sasl_conn_t *conn,
                     const char *user,
                     unsigned userlen,
                     const char *pass,
                     unsigned passlen);

## Description

`int sasl_checkpass(sasl_conn_t *conn,`
`const char *user,`
`unsigned userlen,`
`const char *pass,`
`unsigned passlen)`

  sasl_checkpass will check a plaintext password. This is needed for protocols that had a login method before SASL (for example the LOGIN command in IMAP). The password is checked with the pwcheck_method. See sasl_callbacks(3) for information on how this parameter is set.

## Return value

sasl_checkpass returns an integer which corresponds to one of the following codes. `SASL_OK` indicates that the authentication is complete. All other return codes indicate errors and should either be handled or the authentication session should be quit. See sasl_errors(3) for meanings of return codes.

## Conforming to
