Re: [Condor-users] PASSWD_CACHE_REFRESH in 6.9.4?

[Dan Bradley <dan@xxxxxxxxxxxx>]

Actually, PASSWD_CACHE_REFRESH does not accept expressions.  It requires 
a plain integer.  The only change in semantics is that in 6.9.2, we 
added better validation of input.  Previously, 
PASSWD_CACHE_REFRESH=123+blahblah would silently result in a value of 
123 being used.  In 6.9.2+, condor complains and falls back to the 
default value.

Therefore, the advice that I added to the web page on administering 
large condor pools was incorrect.  Sorry about that!  I have corrected 
that.  Anyway, in 6.9.4, the randomization happens internally, so 
hopefully there is no need to worry about it.

Here's the web page we are talking about, for others who are interested:
