I would argue that it's out of scope -- credential management should be taken care of by your credential management system, be it through a web interface or whatever. Even if it were to be an accepted spec, the chances of all of the client-writers implementing it, and in a reasonable way,

Its OK that they hang around -- in fact, its encouraged. You could set the -U flag on imapd, etc to "1", then the process should die after its first use. -rob On Dec 19, 2007, at 14:56, Mike Eggleston wrote: > I run a small shop and have around ~18 users. Checking just now I have > 70 imap

I enabled it a few weeks ago before I left UMBC, and it certainly seemed to help write performance on the ZFS pool -- we started seeing the larger batched writes on those devices, instead of a constant stream of itty bity IOs caused by the constant fsync'ing. If you feel that your filesyste

We went through a similar discussion last year in OpenAFS land, and came the same conclusion -- basically, if your filesystem is reasonably reliable (such as ZFS is), and you can trust your underlying storage not to lose transactions that are in-cache during a 'bad event', the added benefi
