[pkg-horde] Bug#629006: horde3: Notice "Undefined index: token_lifetime" when saving options. Saving option fails.

[Morten M Neergaard]

It appears that these notices are not normally printed. Not sure exactly
what triggers the full stacktrace, but the average end user should only
see the following error message (and not the PHP errors):

    This request cannot be completed because the link you followed or
    the form you submitted was only valid for minutes. Please try again
    now.

As you can see, the number of minutes is not printed because the
token_lifetime setting was not found :)

Cheers!
