mpm-itk and mod_fcgid

[AZ 9901 <az9901@gmail.com>]

Hello all,

I run into troubles using mod_fcgid (for PHP) and mpm-itk together.
I use Debian stable version / Apache 2.2.22.

As soon as I add the ITK directive "AssignUserID" to my vhost, specifying a different user than the global Apache one, mod_fcgid fails returning the following error :
[Sun Jul 28 15:09:37 2013] [emerg] [client x.x.x.x] (13)Permission denied: mod_fcgid: can't lock process table in pid 1973

I noted that the socket file is created with permissions 700.
So, as a test, I tried the following, in fcgid_proc_unix.c, I replaced :
   rv = apr_file_perms_set(unix_addr.sun_path,
                           APR_FPROT_UREAD|APR_FPROT_UWRITE|APR_FPROT_UEXECUTE);
by :
   rv = apr_file_perms_set(unix_addr.sun_path,
                           APR_FPROT_UREAD|APR_FPROT_UWRITE|APR_FPROT_UEXECUTE|APR_FPROT_GREAD|APR_FPROT_GWRITE|APR_FPROT_GEXECUTE|APR_FPROT_WREAD|APR_FPROT_WWRITE|APR_FPROT_WEXECUTE);

The socket is then created with 777 permissions, but it does not solve the issue.

Certainly that the issue is somewhere else, perhaps Apache tries to instance mod_fcgid with global Apache user instead of ITK defined user.

Could you help me with that ?
Perhaps a patch already exists ?

Thank you very much !

Best regards,

Ben
