How to interact with Cpanel database

[Bogdan]

Hi,

I am designing a custom client portal and I would like to use the same login information as for Cpanel.
My question is: is there any way in witch I can interact with the cpanel login information?
In witch files are the login info stored?

I tried searching on the cpanel forum but I didn't found anything relevant.

Thanks.

The accounts themselves are standard unix accounts. Other apps like ftp and email use their own mechanism, which differs per program.
