How to enable disk quotas in Lion Server (OS X 10.7.5)?

Hello, all. I am having an impossible time trying to set disk quotas in Lion Sever (OS X 10.7.5) and have searched these (and many other) forums to no avail. Basically, as my network will have mixed PC and Mac users I have set the primary home share folder to SMB. I understand that quotas should be enabled without a hitch under AFP, but this will not suffice for PC clients. I have set quotas in WGM but when I check from a remote connection it shows folder capactiy as the volume's total capacity where the home folder resides.

As the latest version of Server Admin does not have a file share section, how can I do this? I understand it may be possible from the terminal, but having little experience with terminal I would prefer not set it myself (man quotaon was less than helpful).

Thank you in advance for any help.
