There's 3 levels your dealing with local, intranet, and internet. 127.0.0.1 is local to that machine only 10.10.100.3 is intranet ?.?.?.? is internet
It all depends on how Imail, Open ldap, the web interfaces are written and configured. If the web interfaces are written as server side, then 127.0.0.1 might work because it's running on itself. But if the web interfaces runs on client side....127.0.0.1 is on the client pc, not the server...thus the query wouldn't work. Open LDAP's querying will respond on 127.0.0.1 if the query is made on the local machine and if it's told to "listen" on that ip address. Your only options are to have it all work completely correct are: 1. Resolve your dns issues internally and configure accordingly. 2. lock down the imail server and place it on the outside of your firewall (ie internet) Take my word for it...I tried to do what your doing many years ago when I was new also. ----- Original Message ----- From: "Patrick Ouellet" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, April 15, 2004 12:53 PM Subject: Re: [IMail Forum] LDAP acces with external tool > Hi Brad > > The point wasn't there.
