Apart from being confusing, it effectively overrides libuser's use of lid.

Right.

I'm pretty sure that naming conflicts in /usr/bin have happened before
in Fedora, I'm not sure how they were resolved.

True.

Anecdotal evidence from bug reports is that if people use the libuser
command-line tools at all, they use them mainly for LDAP.
Anyway, we can't please both sets of users at the same time. If the
above-mentioned reference to previous naming conflicts in Fedora does
not result in a generally-acceptable solution, what about the
following?
lid is renamed in both packages to lid-libuser and lid-idutils (or
something), respectively. Both packages ship an alias script
somewhere in /etc. A new package is created, providing a /usr/bin/lid
script, that instructs the user to add the alias to their ~/.bashrc,
and fails.[1]

[1] The script could also automatically run one of the lid's, if there
were only one installed - but then merely installing a new package
could break user's workflow, which I think is undesirable.
