# sasl\_server\_init(3)

SASL server authentication initialization

## NAME

sasl\_server\_init - SASL server authentication initialization

## SYNOPSIS

```
#include <sasl/sasl.h>

int sasl_server_init(const sasl_callback_t *callbacks,
                     const char *appname);
```

## DESCRIPTION

**sasl\_server\_init()** initializes SASL. It must be called before any calls to sasl\_server\_start, and only once per process. This call initializes all SASL mechanism drivers (e.g. authentication mechanisms). These are usually found in the /usr/lib/sasl2 directory but the directory may be overridden with the SASL\_PATH environment variable (or at compile time).

*callbacks* specifies the base callbacks for all client connections. See the sasl\_callbacks man page for more information.

*appname* is the name of the application. It is used for where to find the default configuration file.

## RETURN VALUE

sasl\_server\_init returns an integer which corresponds to one of the SASL error codes. SASL\_OK is the only one that indicates success. All others indicate errors and should either be handled or the authentication session should be quit.

## CONFORMING TO

RFC 4422
