Scenario:
1. IIS anonymous authentication turnned on
2. Web.config contained:
<authentication mode="Windows" />
<identity impersonate="true" userName="localuser" password="real
password" />
3. In Web application form , guest fill data and updated to backend
database, whcich is an mdb file.
Every thing is ok when "localuser" is in Administrators group.
For minimum privileges principle, I change "localuser" to "Power users"
group, the web application encounter error with following stack:
===================================
[OleDbException (0x80004005): 無法指出的錯誤]

==================================
I think that is a kind of "not enough permission", but how to fix it.
thanks.
