Received from an employee at a Polish university in spring of 2014:

Just for your information (to add to the curiosities list), I have found
the formal reason for the requirement to change passwords every 30 days
- it is the regulation issued by the Ministry of Internal Affairs and
Administration in Poland, and it applies to all IT systems processing
personal data. Full text in Polish is here:
http://www.giodo.gov.pl/plik/id_p/521/j/pl/
The interesting phrase is in the attachment, point 4.IV.2:
"W przypadku gdy do uwierzytelniania użytkowników używa się hasła, jego
zmiana następuje nie rzadziej niż co 30 dni. Hasło składa się co
najmniej z 6 znaków."
Rough translation: "In case when users are authenticated by password,
the password must be changed no less than once every 30 days. The
password must be at least 6 characters long."

Sounds fair to me. I don't know you, your students or your university,
so I cannot do your risk analysis. In our paranoid world it still is
important to remember that most people don't want to become criminals
even if the opportunity exists.
