Hi Brew,
Well this is a new project and we will import our users to this system after the project is done.
yes, the same usernames in different applications are the same user and they should be able to login with their single username and password in each application. From those applications I'm going to use, half has built-in PgSQL capabilities and half have MySQL as their databases.
I also have CAS ( Centeral Authentication Service ) in mind for SSO ( Single Sign On ). They also have a phpCAS class that authenticates the users against the CAS server and this way the user won't need to login again in each application as phpCAS will check their ticket to see if they're logged in or not.
Also I can do the project in another way, not using PgSQL and using their native databases. This way I will have duplication of data in each application as each application will store its username & password in its own database. But a modification should be done in all the applications to prevent the users from signing up and editing their profile inside the application, and then write a central signup & profile editing section where users can update their passwords for example, and this central profile editing will update the password stored in all databased ( suppose 10 databases ! ).
But I think this way is really silly :( As it will cause the server to handle too many queries!
This was the description of my project. If anyone have a better solution please let me know. I also have researched about using LDAP as the main DB server but seems it can only be used as the CAS and not the main DB for applications as it's main use is as a directory and can not be used in a high volume of changing data environment. Also very much modification should be done in each application to be able to talk to LDAP server!!
Also I have another question : do I need to edit MySQL queries very much in my PHP applications to interact with a PgSQL or not? Because most of the queries are the same and maybe very few should be changed ( as far as I know! ).

It seems to me you have greater issues than simply combining the three username and password tables!!!
What if there are existing users on the three different systems with the same user name? Are they garanteed to be the same person? Maybe so, if they have the same password, but what will you do if they have different passwords?
But beyond that, from what you say, you have to convert three different systems from whatever database programs you are using now to postgreSQL. The current databases are doing more than just keeping track of users and passwords, right? Possibly you plan to keep the existing database program and just use postgreSQL to log in?
And do you hope your users will log in once and go back and forth between your aplications without logging in again, or not?
At any rate, unless the applications are very simple, there is a lot more work to be done than simply joining the three password tables together!!!!!

PHP2 has its own table called logins and have 2 fields "login_name" & "login_password". and my Java program have a table called profiles with "plogin" and "ppass". suppose that the password field in all the programs are MD5. Now I want to integrate them. I have read some PgSQL help books and it seems that there are many options that PgSQL offers for this, like inheritance, views and join. but I don't know exactly what to do. Can anyone help please?
