Joel, Please post your config.pm. When you say you've made some progress, what does that mean exactly. Have you been able to have your customer end authenticate at all with AD? I'm trying to do the same thing, but seem to be having problems aswell, so a sample config.pm to compare mine to would be helpful. Thanks, Mike Pietersen, A+, MCP All State Fastener Corporation IT (586) 498-1388 ________________________________ From: otrs-bounces@otrs.org [mailto:otrs-bounces@otrs.org] On Behalf Of Hames, Joel Sent: Tuesday, January 17, 2006 6:47 PM To: otrs@otrs.org Subject: [otrs] Active Directory/LDAP authentication problem I have made some progress in getting this working, but I now have this error on my customer login screen: IO::Socket::INET: connect: Unknown error at D:/Programs/OTRS/otrs//Kernel/System/CustomerUser/LDAP.pm line 63. I am not sure if this is an inability to connect problem, or if it is an inability to authenticate against Active Directory. I can post my config.pm, if necessary.
