EXECUTE AS LOGIN mit deaktiviertem Account

Kürzlich I experienced another surprise with EXECUTE AS LOGIN. It is quite possible to carry out the impersonation even for a disabled or even deleted login. Here's an example:

I put on Windows a user "test", for which I then create a login in SQL Server. Then I set for this login to a user on the Northwind database and SELECT permissions to give him. Here's the script this:

use [master]
go
create login [deep thought \\ test] from windows
with default_database = [master]
go
use [northwind]
go
createuser [deep thought \\ test] for login [Deep thought \\ test]
go
use [northwind]
go
exec sp_addrolemember N'db_datareader 'N'DeepThought \\ test'
go

The database user can [deep thought \\ test] now on the Northwind database as data query. By EXECUTE AS LOGIN untetr another, this can also log in to be checked, like so:

execute as login = 'deep thought \\ test' select * from Customers

revert

The SELECT statement works without problems.
Now, if the login is disabled and also the login is denied permission to log on, then one would think so, that the above SELECT in the context of EXECUTE AS LOGIN not working anymore. This is not so! If I login with this script Override:

use [master]
go
deny connect sql to [deep thought \\ test]
go
old login [deep thought \\ test] disable
go

then does the SELECT statement in the context of the disabled logins as before, although an application in the security context is not at all possible! Now, one might even argue that it's not about to check whether the test is allowed to login at all. EXECUTE AS LOGIN tests easy, which would be allowed in the security context of the application if the application for successful would run. I was there but a bit confused, because I use EXECUTE AS often to test this behavior and I find it quite strange.

iPhone Firmware 3.1 und Tethering

I must get rid of just once: to

The ability to use tethering for me was a major factor in the decision for the iPhone and I have specially selected a tariff with a correspondingly high data volume. The contract seller in the shop assured me at the signing and that tethering will work with the new firmware 3.0.

And now? T-Mobile and Apple have agreed to configure tethering with the new firmware 3.1 so that t-mobile for this extra can collect fees. I'll be there to play on No way. It's just ridiculous when you confined to the technical capabilities of the iPhone and unlock only charges.

Yes, I know is somewhere in the small print that tethering is not part of the contract. But I wonder at all, including small print in contracts should be good. This is but one and pursue only the goal, the signatories to conceal anything.

course it is normal for someone who has gone through a lot of skill (or what have you) get a monopoly, this advantage also. Sometimes, however, since even on the feeling that this exploitation is almost immoral.

Ok, self-inflicted misery, one could say now. Why the decision for t-mobile? But if you want to have an iPhone now once and gives the false promises of service delivery as well as faith? What then? Inevitably, one t-mobile are considered.

Ultimately we think but at t-mobile is not up to the end here, because this approach does so only to the other mobile providers in the cards. The first can sit back and relax and watch the tethering theater from the stands. Meanwhile, drives them t-mobile, the angry customers into the arms. If it has been found that the t-mobile concept the extra fee for tethering rises, then the others can easily with the former t-mobile customers who are now so their customers, just moved so and charge a similar brushed. If not, it comes up, then they have, after all, nor the ex-t-mobile customers, is not it?

There were also dismissed a number of social workers whose job description has since is severely damaged. The image of the beaten to death babies, lying in his bloody feces are pursuing social workers and politicians in the UK for a long time.
