We decided to store the configuration in the SSO database. While the MMC snap-in provided by Microsoft is good enough, there is no option to bulk edit the Key/Value pairs stored in the SSO database. The snap-in does allow to export the file, but its encrypted and hence cannot be edited outside of the snap-in.
We wrote a small utility which allows to decrypt/encrypt the files exportable from the snap-in. Once exported, the file can be decrypted, edited in a text editor, encrypted again and can be imported in the snap-in to create the key/value pairs in the SSO database.
The utility can be downloaded from here.
