[Zope-DB] Change login for database connection

[Thomas_Janke@prisma-edv.de]

Hi,

I would like to present the user of a database a form where he enters his
database user name and pass. This information shall be used to establisch a
connection to the database. It is necessary, because most of the logic of
the database should be in the database itself and not inside the
Web-interface.

Alternatively, I would like to know, how to close and establish a
connection from a DTML-document/method or a python_script. And how to alter
the properties of a database connection object in between.

Thank you so much for any help.
