Greetings,
Let me give a brief history first (before anyone flames me for this post).
Recently I got interested in SF-Offsite and downloaded SF2.5 and started setting it up. In due course I landed in enough problems. However, while checking some of the documents, I came across this project - nss-mysql. I left SF2.5 for the time being and started working on making my linux box more useful by using NSS. Since I want a port for postgresql I downloaded the sources and tried to tweak around.
However, I found that database-neutrality is not one of the major objectives of this project (I should have guessed it from the title of the project itself!)
I was forced to rewrite the code - the whole code. That started the nss-sqldb project. In a way nss-mysql is the parent of this project and that is the reason this message is being posted here.

The first source tar-ball is released on source forge. Checkout http://sourceforge.net/projects/nss-sqldb.
The features of the initial release are as follows:
1. Supports passwd and shadow (no group support yet)
2. Supports postgresql database
I created an abstraction layer for database. There is a README.Databases file in the top-directory. I think if any of the mysql gurus spend a little time - a database layer can be created for nss-sqldb in no time. I request you to give it a try and provide me with feedback.

Thanks for your time.

Warm Regards
