Installation & Security HOWTO
Administration
Now go to your phpgroupware root in the browser, mine is http://server/~chris/phpgroupware/. Login as your admin user. You will have the default "Verdilak" template and a purple color theme. you can change this in Preferences (link on the top right). On the preferences pages as Admin you can select the Default or Forced preferences. Default only applies to new users but lets them change it later, and Forced will change any existing users too and disables the ability to change it. In these default and forced prefs if you leave an option as "Select One" or leave it blank, the system default will apply and the users will be allowed to change that option. Go ahead and find which template you like for a default by selecting one under Your Preferences then set it to be the default or force it. Note that if you choose Idsociety template it looks best with the Idsociety theme.
By default the only app granted access to is the Administration app. Using this app you can change some site settings without using the setup app, manage users and groups and installed applications, and other things. Let's edit User accounts and edit our Admin user. If you leave the password fields blank the current password will not be changed. To demonstrate how user and group application permissions work, make sure your user is in both Default and Admin groups, leave Administration checked, and check only System Information. Any app you grant access to will not show up until you do any one other thing. This is because the menu list is built before the admin apps runs to save the changes. System Information does not have a menu icon. It's only accessible through the admin app. Now go into User Groups and edit the Admin group. Select Messenger. Now edit the Default group. you will notice the Messenger icon in your menu now. Give the default group access to Addressbook, Calendar, Notify Window, Preferences, User Manual, E-Mail, filemanager, and To Do List. Now submit your changes and edit the default group again. Click the little blue box in the ACL column next to To Do and a new window will open. Here you can use the ACL to grant permissions to users data for other users. Grant Read, Add and Edit for Admins and only Read for Default. Users will also have access to this tool through the Preferences for Apps that support it so they can grant even more granular access. Submit and close the window. Go back to the Administration app, you now have a section for each of the apps you have rights to use. Go into each one and set anything needed for your installation. To use Email be sure to enter your site settings including an SMTP server. The Email app does not use php's built in mail() function nor a local sendmail, it speaks STMP so that it can support more advanced MIME functions like a real email client. Also note here that in order for email to work, your phpgw usernames and passwords MUST be exactly the same as your mail server accounts. If they are not, or you don't want them to be, you will have use the Custom email settings and set it for each user, one at a time.
The Manual app will give you some insight on how to work each of the apps, but be aware that some of the information is out of date.
Hopefully this will give you enough of a start to begin using phpGroupWare for your workgroup needs!
