Hi,
I installed jenkins-1.545, under FreeBSD-10.0RC5.
For this installation, I enabled a feature which I don't
normally use. In the configuration setup,
I enabled security, and used Unix security. This uses the
PAM plugin for Jenkins.
I enabled "Matrix security", and created one user "jenkins"
and gave the user all the permissions.
The "jenkins" user was already created in /etc/passwd.
I validated that I could login as "jenkins" from the command-line.
When I tried to login via the jenkins web interface as "jenkins",
I saw this error traceback in /var/log/jenkins.log:
JNA: Callback org.jvnet.libpam.PAM$1@
66732173 threw the following exception:

and the login failed.
After further investigation of the source code, it looks like in Jenkins,
one of the modules
used in PAM authentication is this one:
http://libpam4j.kohsuke.org/
libpam4j has some hardcoded logic about the size
of certain C data structures such as "struct passwd" gets the logic
wrong, becaue in FreeBSD, those structures have changed since
this code was written.
I am a little less familiar with this module.
Can someone give me advice for how I can
build libpamj, test it, and submit fixes back upstream?
Thanks.
