Title:
freeipa-client: ipa-client-install doesn't modify /etc/nsswitch.conf
on 20.04
Status in freeipa package in Ubuntu:
Incomplete
Bug description:
Hi!
We have Ubuntu 18.04 servers that we're upgrading to 20.04, and we've
found a minor bug.
When running the ipa-client-install tool on Ubuntu 20.04, it installs
everything and enrolls the host, but at the end it skips updating
/etc/nsswitch.conf to add `sss` to anything in /etc/nsswitch.conf.
I haven't looked at the source, but I suspect that the tool doesn't
recognize the exact configuration in /etc/nsswitch.conf as a 'known'
configuration and silently refuses to modify it.
Manually adding `sss` to the passwd, group, shadow, services, and
netgroup lines makes everything work.
Partial output of ipa-client-install:
```

When it says "Check NSS setup manually.", it's really saying
"Configure NSS setup manually".
Here's the resulting /etc/nsswitch.conf file, after manually appending
'sss':
```

# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.
