[Driftstörning] Maintanance on authentication servers

[Björn Sandell]

Next week we will upgrade our authentication servers (kerberos).

On Thursday afternoon logins might be bit slow and for some time it
will not be possible to change passwords or create new accounts.
Apart from that, we do not expect any notisable disturbances.

We will give a (late) notice just before the expected service
interruption.
