It doesn't hang, just takes very very long in large domains.  What you
want is "mkpasswd -d -u YOURUSERNAME >> /etc/passwd".  Though I believe
"mkpasswd -c" already does that without the need to query the domain.

Yes, but you do need the groups.  So, you'll have to add all the domain
groups that your user is a member of to /etc/group, using "mkgroup -d -g
GROUPNAME >> /etc/group" for each group.

It's not a problem, it's a warning that your /etc/group is not up-to-date.

No, it suggests running "mkgroup -l -d". :-)
But don't do that if you have a large domain...  Unless you just want to
leave it to complete overnight.

I wonder if we should add a warning about mkpasswd/mkgroup taking very
long in large domains to the User's Guide?

> and not "mkgroup". Is this better?

10513, IIRC, is "Domain Users".  Try "mkgroup -d -g 'Domain Users' >>
/etc/group" (note the quotes around "Domain Users".

FWIW, I have a patch to setup (that I should submit soon) which will check
the exit codes of postinstall scripts and warn if they didn't complete
properly.
