CURLOPT_SASL_AUTHZID \- authorization identity (identity to act as)
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SASL_AUTHZID, char *authzid);

.SH DESCRIPTION
Pass a char * 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 will be sent to the server, along with the

not provided, which it will then uses internally.

When the \fIauthzid\fP is specified, the use of which is server dependent, it
can be used to access another user's inbox, that the user has been granted
