When a users' password has been changed on the Active Directory, you can use this procedure to remove the user from FileVault and re-add it with his new password.

sudo fdesetup remove -user username
sudo fdesetup add -usertoadd username
Enter the user name: adminusername
Enter the password for user 'adminusername':
Enter the password for the added user 'username':

Where username is the username of the user you want to remove and re-add.
And adminusername is the username of an administrative user.

If you're having problems connecting to a Dell iDrac remote console due to Java not trusting the certificate although it's in the exception list, try this.
The certificate is probably signed by a MD5 intermedia certificate, and that's disabled by default. To enable, this, you need to edit your java.security file.

On Windows, this is located at C:\Program Files (x86)\Java\jre_<version-here>\lib\security\java.security
You need to run your editor as Administrator to be able to modify the file.

Find the line that says:
# jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024

If the line starts with a #, remove the # to uncomment it.
