* We don??™t cover Kerberos in this book. You can find information about Kerberos at http://web.mit.edu/
kerberos/.
?? On some operating systems, suchas Linux, OpenSSL is preinstalled in the correct directories, so you do not
need to do anything special in order to use it.
???We describe links here, but you may prefer copies or even configuring OpenSSL to install in the correct system
locations.

In addition, because sendmail does not trust shared libraries that are not in trusted
locations, be aware that you may also need to link or copy the sasl shared libraries
into the /usr/lib directory:
# cd /usr/lib
# ln -s ../local/lib/libsasl* ?†? V1 link
# cp ../local/lib/libsasl* . ?†? V1 copy
# ln -s ../local/lib/libsasl2* . ?†? V2 link
# cp ../local/lib/libsasl2* . ?†? V2 copy
To tune the SASL library for your site, you need to decide how you want passwords
validated. We cover this next, but first we need to discuss the sasldb database.
Note that the sasldb database provides the means to set up accounts for email that
are separate from the user accounts that normally exist on your machine. If you wish
to use only existing accounts, we have finished tuning your SASL library and you
may skip to ?§5.
