User Management Webapplication

Hi All,

I've a question about user-management when developing webapplications:

Which approach would you people preferre?

1. Create a table in the database with the following columns: username, password, group, rights

use this table to add or remove users from the system and take care of the user rights like reading, writing, updating, deleting to the database.

OR

2. Using sql server 2000 user management, and create logins for every user. The groups, Read/Write/delete/update rights are managed trough the sqlserver 2000 system.

thanks in advance
