As previously mentioned, I have written a nasty bash script to get the user certificate DN for a given username in ARGUS.
This is a step further, it is a WebUI that is seeded by data updated via a script in a cronjob on ARGUS, it requires a shared filesystem (in this case, /mt/admin or it requires ARGUS to have PHP and a WebServer.
It depends on the following:
HTTPD (Apache/Nginx), PHP, PHP-LDAP, ARGUS
The bash/shell script is run on argus to produce an output, every 30minutes should suffice.
The web files only need access to the output file created by the shell script along with a basic webserver running php and php-ldap.
