Linux: keyring-password for wlan needed / legitimate wlan login

Each time i resume my notebook after a suspend to disk-cycle the connection to WLAN hangs with the following message:

 (Die Systemrichtlinien verhinder das Bearbeiten von Netzwerkeinstellungen für alle Benutzer / Enter password for default keyring to unlock)
I tried to fix this via network-manager with adding the hook at the checkbox "Alle Benutzer dürfen dieses Netzwerk verwenden", but this did not help at all.
The point is, that after resuming my login keyring wants a authentication with password again. But this behaviour can be easily changed with the tool seahorse.
(Installation in debian with:  apt-get install seahorse)

After starting seahorse choose "File -> New" and you will get the following dialog:

 Create a new password-keyring (Passwort-Schlüsselbund) -

 Choose a name -

 and do not enter a password (this is not really secure, but if you configure your screensaver to lock your screen with a password, this should not be a problem)

 Confirm an empty password - and the you are done.

At the end you have to delete the old keyring (the one with the password):

This is done with right clicking the appropriate item...

After all this steps you should not see this legitimate-popup anymore...
