I wish I could be more specific.
It took me 10 hours to figure out what was going on, having to boot
repeatedly the machine each time it hanged.
The configuration I was using worked perfectly well on 12 LTS and the
only change I made to fix the problem after the upgrade is the one I
mentioned.
The same thing happened on a second machine which was configured similarly.
So I concluded that this is a situation that may occurr to others as
well and it could save them some time if they knew a solution.
I could not find relevant documentation about the parameter
passwd_compat
except that it appears related to Solaris.
I suspect that this is a legacy configuration that has been preserved by
our system administrators since the time we were using Sun machines in
our network.
Possibily this parameter creates some conflicts on release 14 that make
it to hang the machine.
Someone who knows what passwd_compat does should be able to figure out
the cause.
To replicate the problem it should be enough to configure nsswitch like
this:
passwd: compat
passwd_compat: ldap
After this, try doing add-user and the machine will hang.
Thank you.
