If you enable ssl in apache, you can verify a client certificate. 
If so apache will create a environment variable for you with the name 'SSL_CLIENT_VERIFY' with values 'NONE, SUCCESS, GENEROUS or FAILED:reason'. 
See https://httpd.apache.org/docs/2.0/mod/mod_ssl.html 


NONE: client has no cert 
SUCCESS = cert is valid 
GENEROUS = says only that some kind of certificate was sent at all 
FAILED:reason = auth with the cert failed
