.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SASL_AUTHZID, char *authzid);
.fi
.SH DESCRIPTION
Pass a char pointer as parameter, which should be pointing to the
null\-terminated authorization identity (\fIauthzid\fP) for the transfer. Only
applicable to the PLAIN SASL authentication mechanism where it is optional.

When not specified only the authentication identity (\fIauthcid\fP) as
specified by the username is sent to the server, along with the password. The
server derives a \fIauthzid\fP from the \fIauthcid\fP when not provided, which
it then uses internally.

When the \fIauthzid\fP is specified, the use of which is server dependent, it
can be used to access another user\(aqs inbox, that the user has been granted
access to, or a shared mailbox for example.
