[krbdev.mit.edu #8011] Problem regarding 'Pass phrase' prompt length limit in pkinit plugins

[Neng Xue via RT]

Hi,

I am Neng Xue currently working in MIT dropin project in Oracle Solaris 
group as a software developer. Recently we noticed an occasionally 
happened test failure of python test *t_pkinit.py[54]* in our build 
environment. Then I tried to debug into the issue. I noticed that after 
reading the certs file for test case 54, the pass phrase prompt did not 
even appear before reporting the test case failure. So I turned on the 
-DDEBUG option for debug mode. I saw the following error message:

Prompt string, 'Pass phrase for 
/*****/*******/*****/*****/user-enc.p12', is too long!

The prompt_string length limit is set to 128 characters, in our build 
environment, the file path length around 100 which makes the total 
length of prompt_string exceeding the 128 limit. I was wondering is 
there a particular reason for this limit? Or is there a workaround for 
this issue? Thanks!
