Hi
I need a litle help for this:

Current scenery:

We have 4 NT domains servers in different sites
Some users have their login registered in all or some domains.

Databases: (one server or more located in each domain)

We have a mix of windows 2K, windows 2003, solaris, AIX and linux servers
like this:
oracle 10g (windows 2003)
oracle 9.2.0.4 (linux and windows 2003)
oracle 8.1.74 (solaris, aix and windows 2k).
The users are registered in all databases that they need to access.

Connections to the databases:

Local authentication (tnsnames.ora in all client machines)
Our applications use the domain login that is repassed to a proper system of
authorizations which send the username and password to the database.
We have applications WEB using JDBC and HTTP also.

We do not use OID(Oracle Internet Directory) or any other oracle security
method.

Future scenery:

We are switching to Active Directory and also we'll have only one domain.
We do not like to recreate all AD users in our databases manually that would
be a hard work;
We would like that the authentication on Oracle be made by AD. I belive that
will not be necessery to create all users in the databases manually and also
that all synchronization will be made automatically. Am I correct?
Questions:
Will this integration works with UNIX and Linux OS?

Will I have to acquire some additional Oracle product?
Does anybody can indicate a documentation that shows how to implement this
integration step by step ?

And finally: Does anybody knows if this integration works well? Remember
that I have databases distributed in four sites.

Any help will be appreciated.
