Comment 1 Cristian Iorga 2013-07-29 14:39:36 UTC 
poky version: master commit 67864ca79da08df752487a3a4e1a975546da123d.
Comment 2 Cristian Iorga 2013-07-29 14:53:57 UTC 
On a initial investigation seems that:
http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=b5c49e6032a05f1c452010010f97b81d9100196f is related.
Reverting this patch makes the issue go away.
I might be wrong.
Comment 3 Saul Wold 2013-08-01 06:29:14 UTC 
Something in core-image-basic is requiring PAM when pam is disabled, pam is only enabled for LSB based builds, so using bitbake -g -u depexp might show what is depending on pam and this should be setup to use PACKAGECONFIG
Comment 5 Saul Wold 2013-08-07 22:26:25 UTC 
See prior comment for commit
Comment 6 Razvan Ionescu 2013-10-08 09:44:26 UTC 
I can reproduce the bug using: poky: 1cf75b5fd35026f90fb606897d4cb902ff0d960c .
Also, the command bitbake -g -u depexp returns an error stating: NameError: global name 'logger' is not defined

It is hapenning also on a newer poky, such as: dora:a02280f99f05b1c21de2a78de9222a2f62a0dabc (1.5 M5 RC6).
Comment 7 Saul Wold 2013-10-15 22:22:57 UTC 
I see what happened, I already had a libpam built so it did not warn me on 
subsequent runs.  If I cleansstate between runs I found the issue again, turns 
out libuser has a hard depenedency on libpam, so I have a fix for that now.
Comment 9 Cristian Iorga 2014-03-24 09:20:19 UTC 
Reopened the issue, issue is still reproducible while building a core-image-lsb:

WARNING: Building libpam but 'pam' isn't in DISTRO_FEATURES, PAM won't work correctly

Present in: 
poky master HEAD: commit 24979a1f7ecc155cf36f61ffb2d2a32c2fb64734.
Comment 10 Cristian Iorga 2014-03-31 07:19:25 UTC 
My re-open of the issue was a mistake, because building a proper core-image-lsb requires setting accordingly the distro, which in case of core-image-lsb is:
DISTRO = "poky-lsb"
I didn't do that config, as such I received the proper warning:
"WARNING: Building libpam but 'pam' isn't in DISTRO_FEATURES, PAM won't work correctly".
Which is correct.

Regards,
Cristian
