Can't remove user from the role or group

[ChristineBao]

Report from Autodesk QA:

1. 1. go to mapadmin page (​http://localhost/mapguide2012/mapadmin/)[[BR]]
2. add user (e.g 'qa1')
   
3. assign roles to the new user , ticking both Administrator role and Map Author role
   
4. enter 'manage users' to make sure the role assignment is successful
   
5. enter 'Assign Roles' page again, uncheck the roles for 'qa1' and save
   
6. enter 'manage users' page to check the 'qa1' setting
   

result:
for 'qa1', it still has the roles 'Adminsitrator' and 'Author' assigned.

expecation:
'qa1' has no roles assigned.

Tech assessment:

This is caused by the xQuery not correct. The role xml in side MgSiteResourceContents.dbxml is:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><Role xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Role-1.0.0.xsd">
	<Description>Administrator role</Description>
	<Users>
		<User>
			<Name>Administrator</Name>
		</User>
		<User>
			<Name>test</Name>
		</User>
	</Users>
	<Groups>
	</Groups>
</Role>

According to the xml structure, modify the xQuery string to something like:

delete nodes collection('MgSiteResourceContents.dbxml')/Role[starts-with(Description, "Administrator")]/Users/User[Name="test"]

Test in MapGuide and pass.
