Yes, my intention is to run the sqwebmail CGI stub
binary under suEXEC, not the sqwebmail daemon process
under suEXEC. I understand and appreciate the
SqWebMail's new architecture.
I managed to get the sqwebmail CGI stub binary run
under suEXEC. The problem was I patched the
sqwebmail/sqwebmail.c. Once I reversed sqwebmail.c to
it's original code, it runs under suEXEC without a
problem.
The objective of my patch is to get the login domain
from an environment variable named LOGINDOMAIN, not
from CGI. So that users are not required to type or
select the domain name. I disabled getting the login
domain from CGI in sqwebmail/sqwebmail.c and replaced
with a line as indicated in the �<<== New line� in
the following code:
if (*(u=cgi("username"))) /* Request to log in */
{
const char *p=cgi("password");
const char *mailboxid;
// const char *u2=cgi("logindomain"); <<== Original
line
const char *u2=getenv("LOGINDOMAIN"); <<== New
line
char *ubuf=malloc(strlen(u)+strlen(u2)+2);
int can_changepwd;
strcpy(ubuf, u);
if (*u2)
strcat(strcat(ubuf, "@"), u2);
This code compiles without any error, but it develops
Apache Error 500 at run time with the following error
message:
Premature end of script headers: sqwebmail
I introduced LOGINDOMAIN to the safe_env_lst[] of
suexec.c of Apache and httpd.conf and ssl.conf. My
other CGI programs run under suEXEC can read the
LOGINDOMAIN environment variable and I can see its
value.
Does the sqwebmail CGI stub binary drops any
environment variable that it was not designed to use?
If that is the case, how do I introduce LOGINDOMAIN
environment variable to sqwebmail CGI stub binary?
If what I'm doing is wrong, please let me know, where
and how do I have to change, to read the login domain
name from LOGINDOMAIN environment variable so that
users do not have to type the domain name?
