-********************************************************************************
-*
-* INSTALL --
-*
-
-To install squid_edir_lookup, you need to do the following.
-
-1- Unpack this tarball.
-2- Port?
- (See PORTING, program was written under a SuSe Linux Enterprise Server 10 SP2 +
- Open Enterprise Server 2 SP1 environment)
-3- Run 'make'.
-4- Run 'make install'. (Or optionally copy 'squid_edir_iplookup' to somewhere.
-5- Edit squid.conf with the following lines as an example:
-
-# Setup External ACL Helper with parameters (if required)
-external_acl_type IPUser ttl=1800 negative_ttl=30 children=10 %SRC /usr/sbin/squid_edir_iplookup
-
-# Next line sets how long the credentials last before re-authentication is required.
-auth_param basic credentialsttl 30 minutes
-
-# Next lines are required, and the actual ACL's may be customized to suit your needs.
-# In this example, the 'Internet_Allowed' and 'Internet_Denied' are Groups that users may
-# be used to control internet access, which can also be stacked against other ACL's.
-# Use of the groups is NOT REQUIRED.
-acl edirectory_users_allowed external IPUser Internet_Allowed
-acl edirectory_users_denied external IPUser Internet_Denied
-
-# Next lines are used to bind ACL's to what they actually do. Remember that Squid's
-# Default is to ALLOW ALL.
-http_access deny edirectory_users_denied
-http_access allow edirectory_users_allowed
-http_access deny all
-
-6- START Squid. With some luck, you should have a blind eDirectory authenticator,
- That is, without the Users' knowledge that there even *IS* a proxy server!

-* ISSUES --
-*
-
-- Possible Spelling errors :)
-
-- IPv6 support has yet to be TESTED in a real IPv6 environment, but the code is in place to read IPv6
- networkAddress fields, please attempt this in a TESTING environment first. Please read the
- README file to contact me regarding IPv6 support development.
-
-- There is a known issue regarding Novell's Client for Windows, that is mostly fixed by using
- version 4.91 SP3+, with the 'Auto-Reconnect' feature not re-populating the networkAddress
- field in eDirectory.
-
-- I have also expereinced an issue related to using NetWare 6.5 (SP6 and lower?) and connection licsensing.
- It appears that whenever a server runs low on connection licsenes, that it SOMETIMES does
- NOT populate the networkAddress fields correctly.
-
-- I *STRONGLY RECOMMEND* using the latest version of the Novell Client in all situations *BEFORE*
- seeking support! You may also want to MAKE SURE your servers also have the latest service packs.
-
-- Majority of Proxy Authentication issues can be resolved by having the users' REBOOT if their networkAddress
- is not correct, or using squid_auth_ldap as a fallback. Check ConsoleOne, etc to verify thier
- networkAddress fields to troubleshoot.
-
-- More PROBLEMS using the helper? Check README for contact information.

-* README --
-*
-
-This program has been written in order to solve the problems associated with running the
-Perl squid_ip_lookup.pl as a squid external helper that has been provided by various
-sources, including Novell, Inc.
-
-The limitations of the Perl script involved memory/cpu utilization, speed, and the lack
-of eDirectory 8.8 support, and IPv6 support.
-
-This program is being provided to the Squid Cache Developers as a donation of code to
-help further develop Squid, and it's seamless integration with a Novell Open Enterprise Server
-deployment. Hopefully one day Novell will include updated versions of squid into their
-mainstream OES releases, such as the 3.1.x code tree.
-
-This program has been used in a STABLE PRODUCTION ENTERPRISE environment for months before
-being released to the Squid Development team, but that does not mean that bugs do not exist.
-
-If they do, please contact myself for right now. chad.naugle@travimp.com.
