As I read it, the OP may be confusing application user logins and the credentials used by the application to access the data base. Individual application users should *NOT* have access directly to the data base by having their individual credentials in the db access list. The application should have a unique set of credentials for accessing the database, and the only way users can gain access to the database should be through the application. Do NOT store data base credentials anywhere in the session or in cookies, either, as that can give people access to your database as well.

Actually the OP is trying to figure out, why it is a good thing to have just one set of db credentials for the application instead of individual credentials for every user.
The DBMS has a fine grained permission control system in place.
The issue about thuis is I need to keep the users dbuser and password in a session or cookie because I need it for every connection to the DB.

On the other hand a common way seems to be to check the users credentials and store just some kind of "LoggedIn = TRUE" and use the credentials of the application for queries. But this way I had to reinvent the access control system within the application.

I'm rather leaning to the 1'st way with individual credentials because I haven't seen convincing arguments against it, yet.

Right now we are talking about a web server that has just a very limited set of local users that might get the idea to snoop in /tmp for session files. AFAIK according to default settings the garbage collection runs not very ofthen on low frequented sites so stale session files could stay in /tmp for months. That is not very comfortable, though.
