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

Plaintext Password Verification Callback

## NAME

sasl\_server\_userdb\_checkpass\_t - Plaintext Password Verification Callback

## 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

**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.

*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.
