I am new to Zimbra.

I was just looking at some of the documents mentioned in Zimbra server code.
I am not able find when the GetPrefsRequest is fired which gets specified or all the users preferences set.
I was able to see the ModifyPrefsRequest which modifies the users preferences.Also I have verified by at the Admin site where users can create accounts and he decide about various features.

Any pointers or suggestions for this query will be highly appreciated.

Thanks
