Thanks Alexander for the quick review!
This patch adds ipa-advise plugins to help configure legacy clients for access
to trusted domain resources. For more details, please read the commit message.
Plugins are currently named "config-redhat-sssd-before-1-9" and
"config-generic-sssd-before-1-9"; suggestions for better names are welcome.
Plugin content heavily inspired by

I would imagine we would have multiple plugins that need their own
templates for pam.conf/sssd.conf. What about introducing
to avoid conflicts?
In this case you use the same templates for both plugins so you might
have <name> as 'legacy', for example.
Another way is to have plugin name in the template, e.g.
Done. I opted for the install/share/advise/<name>/*.template option. The changes
are in the updated patch 52.

You need to check that Schema Compatibility plugin is configured to
serve trusted domain users and groups.
We have two trees:
dn: cn=groups,cn=Schema Compatibility,cn=plugins,cn=config
dn: cn=users,cn=Schema Compatibility,cn=plugins,cn=config
In both of the trees there should be
attribute, with the value according to the tree (i.e. user for

Done. I added a new API command 'compat-is-enabled' (similar to
'adtrust-is-enabled') to facilitate checking whether the Schema Compatibility
plugin is configured. 'compat-is-enabled' is called from the ipa-advise plugin
and the suggestion to run 'ipa-adtrust-install --enable-compat' is printed as
the first piece of advice, when appropriate.
Patch 54 adds the new API command 'compat-is-enabled', while patch 53 is a small
fix which enables IPA API commands to be run from the ipa-advise plugins.

Would it make sense to also add instructions to restore SELinux context
(if needed)? I'm not sure, just throwing the idea for consideration.
I am not sure about this either so I will wait for more opinions about this.
Same comments go for the second plugin.
I also refactored the plugin a bit (added a new base class to avoid code
Updated patches are attached. Patch 52 depends on patches 53 and 54.
One small comment:
I've refactored slapi-nis code to make it more generic and references to
sssd in the configuration options went away, so please change this part

It needs my patch 0112 too -- it changes ipa-adtrust-install to write
proper configuration options to slapi-nis configs.
