Use UID erinstead of name

e.g.
[root@host ~]# docker run --user=lslebodn -ti fedora:26 uname
/usr/bin/docker-current: Error response from daemon: linux spec user: unable to
find user lslebodn: no matching entries in passwd file.

[root@host ~]# docker run --user=`id -u lslebodn` -ti fedora:26 uname
Linux

Thomas,

if I understood correctly, you're runnig freeipa-container, right?

If you are, the --user parameter should receive a user that is already
created in image.
Also, this is not related to the freeipa-server image specifically, but a
general usage of Docker.

You can check more of it in [1] and [2].

If I misunderstood it, please provide more details/context of it.
