Samsung Galaxy S II :: Screen Lock: Only The "password" Option Is Available On New Android 2.3.4 And 2.3.5?

I'm having a problem with the new Android, 2.3.4 while using ActiveSync to connect to my corporete email on Exchange Server ... A corporete policy gets pushed to my phone and I need to accept it. OK, no problem ... I accept it, but the Lock screen settings ( under Settings -> Location And Security -> Change Lock Screen ) only allows the "Password" option, saying the other options,e.g. the PIN way is remotely disabled by administrator, although that is NOT the case. I've double checked with our system admins on this.Our system admins are NOT forcing the "Password" option ... they're OK with just using the PIN, and I had it like that, in the old 2.3.3 version !For this setup ... this will display the long PASSWORD for lock-screen, instead of just a PIN which is what I prefer to to use instead:

* Android 2.3.4
* gingerbread.xwki4 on Samsung Galaxy S2
* Exchange 2007 sp3

This policy is NOT forced by our admins, since this is the policy:Here are my complete Password tab settings on the server, so you can see the admins are NOT requesting this long password ( PIN is enough! ):

Require Password - checked Require alphanumeric password - unchecked <--- attention, this is UNCHECKED.
Enable password recovery - checked
Require encryption on the device - checked

[code].....

But with this update, you need the following for the unlock screen of ActiveSync for Exchange Server:6 letters, and one number in the previous version ( 2.3.4 ) you needed 6 letters, TWO numbers and one sign I want to be able to use ONLY 4 letters PIN, as it is allowed on our network, as you can see in our policy just pasted above in this thread!
