Description of the change

This is the fix for bug 1910611 on Hirsute.

The sssd apparmor profile is outdated with regards to a few aspects:

- It doesn't allow the execution of binaries under /usr/libexec/sssd/*

- It doesn't allow sssd to read configuration files under /etc/sssd/conf.d/*

- It doesn't allow sssd to read files under /etc/gss/mech.d/*

The original bug only complained about the first item, but while investigating I found the other two issues, so I'm fixing them as well.

Here's a PPA with the proposed package:

And autopkgtest is still happy:

autopkgtest [23:17:14]: @@@@@@@@@@@@@@@@@@@@ summary
ldap-user-group-ldap-auth PASS
ldap-user-group-krb5-auth PASS

I'm marking Christian as a reviewer because he also reviewed (and approved) the Focal MP.

Christian, as I said in the Focal MP:

1) There's also a Groovy MP for this:

2) I submitted this same change to Debian here:

Thanks, I've checked the groovy MP as well by now.

Ack on the apparmor changes and in Hirsute the version is ok.

Thanks for the Debian MP as well.
There the piuparts test fail seems legit, not due to your changes but still a legit error as FYI.

You already mentioned the i386 build issues before. I guess you decided that since is b-wait on i386 as well it will be no-change and therefore ok.
I agree if that is the case, but otherwise please speak up.

OTOH i386 - see
Maybe sooner or later i386 will resolve that way, but it does not have to stop/gate this upload.

review: Approve

Thanks for the review, Christian. As we've already discussed during standup, I'm aware of the i386 situation. I went ahead and did the upload.
