Hi Naveen, here's what I have hacked so far: http://svwe10.itex.at/downloads/mod_auth_mysql/ to keep the code more readable I've inserted a new function exists() (borrowed from htpasswd.c) which does for now _only_ check if the certs exists; but should be easily extendable for permission check as you did already. Also I have made all settings configurable for easier testing. At least I get an error in the error_log when a path is entered wrong - unfortunately I've not had the time to compile a SSL-aware mysql server, so not able to test further at the moment... just wanted to share the code here; oh, and I believe also the mysql_init() call is wrong since it takes the mysql_handle and not the mysql_conn which is used for mysql_real_connect()...; fixed that too.
I will also propose it to the author once it works since I know him (see change log where I appear already); then we have a ready solution without patching around... Guenter.
