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. The limitations of the Perl script involved memory/cpu utilization, speed, the lack of eDirectory 8.8 support, and IPv6 support. ## OPTIONS - **-4** Force Addresses to be in IPv4 (0.0.0.0 format). - **-6** Force Addresses to be in IPv6 (:: format). - **-b** *base* Specify **base** DN. For example; **o=ORG** - **-d** Write debug info to stderr. - **-D***binddn* Specify binding DN. For example; **cn=squid,o=ORG** - **-F** *filter* Specify LDAP search filter. For example; **(objectClass=User)** - **-G** Specify if LDAP search group is required. For example; **groupMembership=** - **-h \| --help \| --usage** Display the binary help and command line syntax info using stderr. - **-H** *host* Specify hostname or IP of server - **-p** *port* Port number. - **-P** Use persistent connections. - **-t** *seconds* Timeout factor for persistent connections. Set to **0** for never timeout. Default is **60** seconds. - **-s** *base\|one\|sub* search scope. Defaults to **sub** - **base** object only, - **one** level below the base object or - **sub**tree below the base object - **-u** *attribute* Set userid **attribute .** Default is **cn** - **-v** *1\|2\|3* Set LDAP **version** - **-V** Display version information and exit. - **-W** *password* Specify binding **password** - **-Z** Enable TLS security. ## CONFIGURATION **external\_acl\_type IPUser %SRC /usr/sbin/ext\_edirectory\_userip\_acl**\ **acl edirectory\_users\_allowed external IPUser cn=Internet\_Allowed,ou=ORG,o=BASE** **acl edirectory\_users\_denied external IPUser cn=Internet\_Denied,ou=ORG,o=BASE**\ **http\_access deny edirectory\_users\_denied** **http\_access allow edirectory\_users\_allowed** **http\_access deny all** 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 optional, unless the '-G' option has been passed. Please note that you need to specify the full LDAP object for this, as shown above. ## KNOWN ISSUES 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 contact the author 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 experienced an issue related to using NetWare 6.5 (SP6 and lower?) and connection licensing. It appears that whenever a server runs low on connection licenses, that it I sometimes does not populate the networkAddress fields correctly. Majority of Proxy Authentication issues can be resolved by having the users' **reboot** if their networkAddress is not correct, or using **basic\_ldap\_auth** as a fallback. Check ConsoleOne, etc to verify their networkAddress fields to troubleshoot. ## AUTHOR This program was written by *Chad E. Naugle \* This manual was written by *Chad E.
