Issue Description
FTP server is Windows2008R2 standard.

I already  config FTP sharing according to the document

but I try to login using icd user by FTP, display home directory inaccessible.
Alarm Information
Handling Process
so we add the fileftp group to the FTP Authorization Rules and give full control(I think write and read is also OK). then we test the FTP. log in OK.
Root Cause
I have already done the configuration according to the guidance

but I still can not login using icd user by FTP. I think in these steps are not enough in the document:
The Authentication and Authorization Information dialog box is displayed, as shown in Figure 4.

Figure 4 Authentication and Authorization Information dialog box

In the Authentication area, select the Basic check box.
In the Authorization area, select Specified roles or user groups from the Allow access to drop-down list box, and enter fileftp in the text box.
Select the Read and Write check boxes under Permissions.

Click Finish.
after these steps, I do not think fileftp group including icd,icd1,cms has enough authorizaion to login the server by FTP.
we need to check the FTP Authorization Rules as followings:

right click the icon and choose Edit Permissions. choose Security Page. we see no fileftp group, this is the reason why issue happened.
document needs improving.
