We released a new SSSD beta version as 2.10.0-beta1, unfortunately this caused issues in the rpm build system as this value is set as the Version field but dash is not allowed in this field therefore make rpms was broken.
Fedora guidelines requires to use ~ as a prerelease separator so two NVR versions compare correctly. For example:
2.10.0 < 2.10.0-beta1 2.10.0~beta1 < 2.10.0
We will follow this guideline to make make rpms work again and to avoid any further rpm issues. Next GitHub release will also follow this guideline.
If you need to fix this on your side, you can cherry-pick this patch: https://github.com/SSSD/sssd/commit/eadb872677e4bbf1bae09a6c2a18c90b5bf6fa56
But in general, this should not be needed, as distribution do not use this command.

# SSSD 2.10-beta1 Release Notes
## Highlights
### General information
- **IMPORTANT note for downstream maintainers!**
This release features significant improvements of "running with less privileges (under unprivileged service user)" feature. There is still a `./configure` option `--with-sssd-user=` available that allows downstream package maintainers to choose if support of non-root service user should be built. In case such support is built, a preferred way to configure service user is simply by starting SSSD under this user; for example, using `User=/Group=` options of systemd sssd.service file. Upstream defaults are to build `--with-sssd-user=sssd` and to install systemd service with `User=/Group=sssd`. In this case, only several helper processes - `ldap_child`, `krb5_child` and `selinux_child` - are executed with elevated capabilities (that are now granted using fine grained file capabilities instead of SUID bit). All other SSSD components run without any capabilities. In this scenario it's still possible to re-configure SSSD to run under `root` (if needed for some reason): besides changing `User/Group=` options, some other tweaks of systemd service files are required.
A legacy method to configure a service user - sssd.conf `user` option
- is now deprecated and its support isn’t built by default. It can be
enabled using `--with-conf-service-user-support` `./configure` option if needed (for example, due to backward compatibility requirements of stable releases).
Further, no matter if SSSD is built `--with-sssd-user=sssd` or `--with-sssd-user=root`, when it's configured to run under `root` (in both cases) it still runs without capabilities, the same way as when it's configured to run under `sssd` user. The only difference is from the DAC perspective.
Important note: owner of `/etc/sssd/sssd.conf` file (and snippets) should match the user configured to start SSSD service. Upstream spec file changes ownership of existing `sssd.conf` to `sssd` during package installation for seamless upgrades.
Additionally, this release fixes a large number of issues with "socket activation of responders" feature, making it operable out-of-the-box when the package is built `--with-sssd-user=sssd`. Please take a note, that user configured to run main sssd.service and socket activated responders (if used) should match (i.e. if sssd.service is re-configured from upstream defaults to `root` then responders services also should be re-configured).
Downstream package maintainers are advised to carefully inspect changes in `contrib/sssd.spec.in`, `src/sysv/systemd/*` and `./configure` options that this release brings!
- sssctl `cache-upgrade` command was removed. SSSD performs automatic
upgrades at startup when needed.
- Support of `enumeration` feature (i.e. ability to list all
users/groups using `getent passwd/group` without argument) for AD/IPA providers is deprecated and might be removed in further releases. Those who are interested to keep using it awhile should configure its build explicitly using `--with-extended-enumeration-support` ./configure option.
### New features
- The new tool `sss_ssh_knownhosts` can be used with ssh's
KnownHostsCommand configuration option to retrieve the host's public keys from a remote server (FreeIPA, LDAP, etc.). This new tool, which is more reliable, replaces `sss_ssh_knownhostsproxy`. Please consider switching to using the new tool as the old one will be removed.
### Packaging changes
- Building SSSD now unconditionally requires availability of `ucred`/
`SO_PEERCRED` to enforce certain security checks at runtime (see `man 7 unix` for details).
- SSSD now requires `libini` not older than v1.3
- Explicit `--with-semanage` ./configure switch was removed, going
forward `--with-selinux` includes this.
### Configuration changes
- Default `ldap_id_use_start_tls` value changed from `false` to `true`
for improved security.
- Added a `ldap_use_ppolicy` option for backends with broken ppolicy
extension handling.
- Obsolete `config_file_version` option was removed.
