>As well as the text-based dependency graphs, Bugzilla also
      supports dependency graphing, using a package called 'dot'.
      Exactly how this works is controlled by the 'webdotbase' parameter,
      which can have one of three values:

            will generate the graphs locally

><P
>&#13;            A URL prefix pointing to an installation of the webdot package will

            </P
></LI

      </P

>So, to get this working, install
      <A

      Alternatively, you could set up a webdot server, or use the AT&#38;T 
      public webdot server (the
      default for the webdotbase param). Note that AT&#38;T's server won't work
      if Bugzilla is only accessible using HARTS.

      </P

>&#13;      The existing authentication
      scheme for Bugzilla uses email addresses as the primary user ID, and a
      password to authenticate that user. All places within Bugzilla where
      you need to deal with user ID (e.g assigning a bug) use the email
      address. The LDAP authentication builds on top of this scheme, rather
      than replacing it. The initial log in is done with a username and
      password for the LDAP directory. This then fetches the email address
      from LDAP and authenticates seamlessly in the standard Bugzilla
      authentication scheme using this email address. If an account for this
      address already exists in your Bugzilla system, it will log in to that
      account. If no account for that email address exists, one is created at
      the time of login. (In this case, Bugzilla will attempt to use the
      "displayName" or "cn" attribute to determine the user's full name.)
      After authentication, all other user-related tasks are still handled by
      email address, not LDAP username. You still assign bugs by email
      address, query on users by email address, etc.
      </P
><P
>Using LDAP for Bugzilla authentication requires the 
      Mozilla::LDAP (aka PerLDAP) Perl module. The
      Mozilla::LDAP module in turn requires Netscape's Directory SDK for C.
      After you have installed the SDK, then install the PerLDAP module.
      Mozilla::LDAP and the Directory SDK for C are both 
      <A
HREF="http://www.mozilla.org/directory/"
TARGET="_top"
>available for
      download</A
> from mozilla.org. 
      </P
><P
>&#13;      Set the Param 'useLDAP' to "On" **only** if you will be using an LDAP
      directory for
      authentication. Be very careful when setting up this parameter; if you
      set LDAP authentication, but do not have a valid LDAP directory set up,
      you will not be able to log back in to Bugzilla once you log out. (If
      this happens, you can get back in by manually editing the data/params
      file, and setting useLDAP back to 0.)
      </P
><P
>If using LDAP, you must set the
      three additional parameters: Set LDAPserver to the name (and optionally
      port) of your LDAP server. If no port is specified, it defaults to the
      default port of 389. (e.g "ldap.mycompany.com" or
      "ldap.mycompany.com:1234") Set LDAPBaseDN to the base DN for searching
      for users in your LDAP directory. (e.g. "ou=People,o=MyCompany") uids
      must be unique under the DN specified here. Set LDAPmailattribute to
      the name of the attribute in your LDAP directory which contains the
      primary email address. On most directory servers available, this is
      "mail", but you may need to change this.
      </P
><P
>You can also try using <A
HREF="http://www.openldap.org/"
TARGET="_top"
>&#13;      OpenLDAP</A
> with Bugzilla, using any of a number of administration
      tools.  You should apply the patch attached this bug:
      <A
HREF="http://bugzilla.mozilla.org/show_bug.cgi?id=158630"
TARGET="_top"
>&#13;      http://bugzilla.mozilla.org/show_bug.cgi?id=158630</A
>, then set
      the following object classes for your users:

      <P
></P
><OL
TYPE="1"
><LI
><P
>objectClass: person</P
></LI
><LI
><P
>objectClass: organizationalPerson</P

>objectClass: top</P
></LI
><LI
><P
>objectClass: posixAccount</P
></LI
><LI
><P
>objectClass: shadowAccount</P
></LI
></OL
>

      Please note that this patch <EM
>has not</EM
> yet been
      accepted by the Bugzilla team, and so you may need to do some
      manual tweaking.  That said, it looks like Net::LDAP is probably
      the way to go in the future.

>It is possible for a Bugzilla to execute malicious Javascript
      code. Due to internationalization concerns, we are unable to
      incorporate the code changes necessary to fulfill the CERT advisory
      requirements mentioned in 
      <A

>.
      Executing the following code snippet from a UNIX command shell will
      rectify the problem if your Bugzilla installation is intended for an
      English-speaking audience. As always, be sure your Bugzilla
      installation has a good backup before making changes, and I recommend
      you understand what the script is doing before executing it.</P
