CURLOPT_SASL_AUTHZID(3)

NAME
CURLOPT_SASL_AUTHZID - authorization identity (identity to act as)

SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SASL_AUTHZID, char *authzid);

DESCRIPTION
Pass a char pointer as parameter, which should be pointing to the null-terminated authorization identity (authzid) for the transfer. Only applicable to the PLAIN SASL authentication mechanism where it is optional. When not specified only the authentication identity (authcid) as specified by the username is sent to the server, along with the password. The server derives a authzid from the authcid when not provided, which it then uses internally. When the authzid 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 access to, or a shared mailbox for example. The application does not have to keep the string around after setting this option. Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again.

DEFAULT
blank
