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.
