For a full description but basically PAM is exited uncleanly which 
could lead to things like failure to scrub memory or maybe other 
things with unusual pam modules.

Version-Release number of selected component (if applicable):
openssh-3.1p1-14

How reproducible:
Always

Steps to Reproduce:
1. Install otpw and run via OpenSSH/PAM
2. or write a simple test script and test pam module and run them.
3.

I'm sorry but this bug cannot be easily fixed for RHEL 3 (it is fixed in RHEL 4).
The upstream patch is applicable only to the openssh-3.7p1 and the patch for
openssh-3.6.1p2 would be very invasive with a high risk of regressing other
functionality.
