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
