-===== Wednesday 14-10-2024: 9 AM: Login servers (IDP en LDAP) (NEW ATTEMPT) =====
+===== Wednesday 16-10-2024: 9 AM: Login servers (LDAP) COMPLETED =====
-For logging in, two sets of servers are in use: LDAP, which holds the database of user accounts, and the IDP servers that handle the logins and two-factor authentication on local websites (such as webmail and intranet).

 Switching the LDAP servers should be quick, just a few minutes. There are two LDAP servers so we will make sure that one is running at all times. To be sure the database is in a consistent state, password changes will not be possible around this time.

-Switching the IDP servers may affect existing login sessions on websites, so it might be that users get logged out from webmail or intranet during this switch.
+===== Monday 21-10-2024: 10 AM: Home disk COMPLETED =====
-Existing login sessions on desktops or through ssh will not be affected, and logging in on desktops will work normally.
+<color #c8bfe7>This is the most disruptive change. Logging in on Linux systems will not work without the home disk, and existing sessions may give errors or get stuck. So it is recommended to close applications and save your open files before this migration. It will probably be prudent to log out as well.
-===== Monday 21-10-2024: 10 AM: Home disk =====
+At the same time, we will also move the ''samba'' server, the server that connects the home disk for Windows users in the astrophysical and optical labs. Since the home disk isn't available anyway, this will not cause additional downtime for them (this doesn't affect Windows users on the physics domain such as the support staff)</color>

-===== (date to be decided): License server =====
-During this change, connections for reserved licenses will be disrupted (eg IDL, Mathematica)
+===== Friday 29 november 2024 9 AM: License server DONE =====
+<color #c8bfe7>During this change, connections for reserved licenses will be disrupted (eg IDL, Mathematica). In many cases, the software will recover once the license server is back online in the new location, but that is not something we can guarantee. So make sure you close your session or save your data.
