Windows servers) and Gateway Services for NetWare (to allow Windows clients access files and printers on NetWare
servers).
Replace services or applications that require NDS with commensurate software compatible with Active Directory.
Perform large conversions (such as GroupWise to Exchange) as separate projects.
Migrate the pilot group of users and their files (adapt instructions from the migration steps provided in the " Small
Environment " section). Get the pilot group's feedback, and then set a schedule to migrate additional groups of
users, according to the priorities you have established.
Migrate the rest of the users as appropriate (for example, if you migrate the set of applications they use, it is time
to migrate them as well).

Using Secure Sockets Layer
This section explains how secure sockets layer (SSL) are used in the NAS system. It also explains how to use your own
certificate, if you have one, and how to regenerate your certificate.
Introduction to SSL Certificates
Certificates contain information used to establish system identities over a network. This identification process is called
authentication. Although authentication is similar to conventional forms of identification, certificates enable Web servers and
users to authenticate each other before establishing a connection to create more secure communications. Certificates also
contain encryption values, or keys, that are used in establishing an SSL connection between the client and server. Information,
such as a credit card number, sent over this connection is encrypted so that it cannot be intercepted and used by unauthorized
parties.
Two types of certificates are used in SSL. Each type has its own format and purpose. Client certificates contain personal
information about the clients requesting access to your site, which allows you to positively identify them before allowing them
access to the site. Server certificates contain information about the server, which allows the client to positively identify the
server before sharing sensitive information.
Server Certificates
To activate your Web server's SSL 3.0 security features, you must obtain and install a valid server certificate. Server certificates
are digital identifications containing information about your Web server and the organization sponsoring the server's Web
content. A server certificate enables users to authenticate your server, check the validity of Web content, and establish a secure
connection. The server certificate also contains a public key, which is used in creating a secure connection between the client
and server.
The success of a server certificate as a means of identification depends on whether the user trusts the validity of information
contained in the certificate. For example, a user logging on to your company's website might be hesitant to provide credit card
information, despite having viewed the contents of your company's server certificate. This might be especially true if your
company is new and not well known.
For this reason, certificates are sometimes issued and endorsed by a mutually trusted, third-party organization, called a
certification authority. The certification authority's primary responsibility is confirming the identity of those seeking a certificate,
thus ensuring the validity of the identification information contained in the certificate.
Alternatively, depending on your organization's relationship with its website users, you can issue your own server certificates.
For example, in the case of a large corporate intranet handling employee payroll and benefits information, corporate
management might decide to maintain a certificate server and assume responsibility for validating identification information and
