This is information regarding the db_info program.
After configuring, making, installing, and using the module, a file will be created for the database (/tmp/mod_auth_openid.db by default). Return to the mod_auth_openid directory and type:
make db_info
This will create an executable in the current directory named ‘'’db_info’’’. Use the program like:
./db_info /path/to/db/file.db
It will print out the number of sessions, associations, and nonces in the database.
You can also use the –enable-debug configuration option to get debugging information in the apache 2 error log.
