Hello, I’m trying to setup global address book using LDAP and follow your article. The difference is I’m using Centos 5.4. During the setup, I found some things I would like to ask:
1. What are the perl modules in no. 4 function for?
2. The link in no. 7 doesn’t exist anymore. Tried to find in other place but failed, can you please update that?
Thanks
The perl modules were needed for webmin. They probably are not needed anymore.
The link in step 7 has been restored.
Thanks for the update Lee. I’ll continue to test after my computer repaired. BTW, can we use this global address book in Microsoft Outlook?
