# sasl\_server\_userdb\_checkpass\_t(3)

Cyrus SASL documentation

## NAME

sasl\_server\_userdb\_checkpass\_t - Cyrus SASL documentation

## SYNOPSIS

```
#include <sasl/sasl.h>
int sasl_server_userdb_checkpass_t(sasl_conn_t *conn,
        void *context,
        const char *user,
        const char *pass,
        unsigned passlen,
        struct propctx *propctx)
```

## DESCRIPTION

- **int sasl\_server\_userdb\_checkpass\_t(sasl\_conn\_t \*conn,**

  - **void \*context,**

  - **const char \*user,**

  - **const char \*pass,**

  - **unsigned passlen,**

  - **struct propctx \*propctx)**

  **sasl\_server\_userdb\_checkpass\_t()** is used to verify a plaintext password against the callback supplier’s user database. This is to allow additional ways to encode the userPassword property.

  - **Parameters**

    - •

      **conn** – is the SASL connection context

    - •

      **context** – context from the callback record

    - •

      **user** – NUL terminated user name with *user@realm* syntax

    - •

      **pass** – password to check (may not be NUL terminated)

    - •

      **passlen** – length of the password

    - •

      **propctx** – property context to fill in with userPassword

## RETURN VALUE

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

Other return codes indicate errors and should be handled.
