+The OpenVPN Auth-LDAP Plugin implements username/password authentication
+via LDAP for OpenVPN 2.x.
+
+Features
+ * User authentication against LDAP
+ * Simple Apache-style configuration file
+ * LDAP group-based access restrictions
+ * Integration with the OpenBSD packet filter, support adding and removing
+ VPN clients from PF tables based on group membership
+ * Tested against OpenLDAP, the plugin will authenticate any LDAP server
+ that supports LDAP simple binds -- including Active Directory.
+
+Building the package
+ When building this package you will need the source for the OpenVPN
+ release that is installed on your VPN server.
+ For Slackware 13.1 this is openvpn-2.1.1, as specified in the .info
+ file.
+ This is so openvpn-auth-ldap can build against the OpenVPN plugin header
+ files for your particular version of OpenVPN.
+
+Requires the re2c package (can be found on SlackBuilds)

+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
