How can I give an user the right to change passwords

Question

I'm still absolute server beginner, so I have to ask here.
How can I give users the right to change passwords or to view calendars?
I didn't find it, yet.
I've found an option to change rights, when I click on the user with two fingers (right mouse button). But all options in this menue are grey.

Hi Holger,
These are two fundamentally different issues. I'll try to address them each. For both you will need to have OpenDirectory set up (see the Users Next Steps list in the Server app). Once that is done. Additionally you will need the Server Admin Tools 10.7. Once you have them installed, you can specify the OpenDirectory password requirements for users
User Passwords in OpenDirectory
On the server, open Server Admin app.
Connect to you server, then click on the OpenDirectory service.
Click on the Settings icon.
Click on the Policies tab.
Click on the Passwords sub-tab, and you can set all the criteria for password requirements here.
Resetting Passwords
Users must log in as network users on the client computer.
Once logged in, to change the password, open System Preferences.
Click on Users & Groups.
The user icon will be a silhouette with stars in the background. This means it is a network user. Click on the Password tab at the top.
Click the Change Password ... button to change the password.
Calendars in iCal are much like RSS feeds: users need to subscribe to them, like we discussed in our other posting. Network users will automatically be given a network iCal calendar, and will be automatically subscribed to it. However, if you want to automatically add subscribed calendars to network user's accounts, you will need to use ProfileManager.
On the server, open Server app.
Click on the Profile Manager menu item.
Make sure that iCal service is running (green indicator next to it). Click on the "Include configuration for services: ...". Make sure the iCal icon is listed there.
Click the "Sign configuration profiles" checkbox.
Turn Profile Manager on.
Once Profile Manager has loaded (the gear at the bottom right will no longer be spinning), go ahead and click the Open Profile Manager link.
Log into Profile Manager as your directory admin user.
Click on the Groups menu item to give all users of a specific group access to the wiki calendar. This is best if you have a wiki for a group and want to share that calendar. Use the Everyone group to add this calendar for all users.
Click on Users to give access to only specific users.
Edit the profile for the group(s) or user(s) you selected by highlighting that group and clicking the edit button.
Scroll down and select the CalDav item on the left.
Click configure. Here you will need to enter the specific details for that callendar based on the subscription details you get when subscribing to the calendar via the wiki.
After all that you still need to configure each client computer to be set up for profile management, which really is a topic of its own. I recommend the following tutorials:
Installing OS X Lion Server
OS X Lion Server Administration Tool Tour
Setting Up Profile Manager on OS X Lion Server
Using Profile Manager on OS X Lion Server
Hope this helps, good luck!
