[OpenAFS] OpenAFS implementation questions.

[Brady Catherman]

I am currently considering moving our environment to OpenAFS but  
before I can switch I need to make sure a few things are going to  
keep working..

We have users that use or systems for months on end without logging  
off and I am concerned that the kerberos ticket they are being issued  
will expire. Having them log back into kerberos/openafs isn't really  
a good option for us (I am having a hard enough time selling even the  
basic conversion, let alone anything that requires user action!)

Is there an easy way around this with OpenAFS? I have tried setting  
the length of our kerberos tickets higher but the most it will give  
me is 7 days. Is there another way to do this?
