# gsasl\_server\_callback\_gssapi\_set(3)

API function

## NAME

gsasl\_server\_callback\_gssapi\_set - API function

## SYNOPSIS

**#include \<gsasl.h\>**

**void gsasl\_server\_callback\_gssapi\_set(Gsasl \*** *ctx***, Gsasl\_server\_callback\_gssapi** *cb***);**

## ARGUMENTS

- Gsasl \* ctx

  libgsasl handle.

- Gsasl\_server\_callback\_gssapi cb

  callback function

## DESCRIPTION

Specify the callback function to use in the server for checking if a GSSAPI user is authorized for username (by, e.g., calling krb5\_kuserok).  The function should return GSASL\_OK if the user should be permitted access, or an error code such as GSASL\_AUTHENTICATION\_ERROR on failure.  The function can be later retrieved using **gsasl\_server\_callback\_gssapi\_get()**.

## DEPRECATED

This function is part of the old callback interface. The new interface uses **gsasl\_callback\_set()** to set the application callback, and uses **gsasl\_callback()** or **gsasl\_property\_get()** to invoke the callback for certain properties.
