There are two backends for Squirrelmail: the standard backend stores users' profile/preferences in text files (file_prefs.php), and the MySQL one stores them in a MySQL database (db_prefs.php).

This one adds an LDAP backend. However, things are treated much differently, due to the difference in nature between LDAP and other databases. Namely: LDAP writes are expensive. Extensive caching is used to reduce the overhead on the LDAP server, especially in a setup with a lot of users.

This makes a big difference, from the user's point of view. Whenever changing some option, the change is for the current session only. The change will only be saved permanently, if and only if the user logs out from Squirrelmail, thus ending the session.
