help text for token_duration confusing
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1197973
Description of problem:
The help text provided for token_duration in the administer -> settings -> provisioning -> token_duration is confusing. It suggests that specifying a value of zero disabled the time-out (meaning the token will never time-out), while it actually means that no token will be generated at all, which will make unattended provisioning across subnets impossible.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
"Time in minutes installation tokens should be valid for, 0 to disable"
"Time in minutes installation tokens should be valid for, 0 to disable token-generation"
Suggestion to remove the possibility to disable token generation. This means check that the value will always be > 0. Then change the help text to "Time in minutes installation tokens should be valid for"
