After updating systemd to version 246.16-150300.7.39.1.x86_64 on SLES 15 users cannot authenticate. FAILURE: 604 /etc/pam.d/common-auth does not appear to be configured to use SAS. (4256473)

After updating systemd to version 246.16-150300.7.39.1.x86_64 on SLES 15 users cannot authenticate.

vastool status shows:
FAILURE: 604 /etc/pam.d/common-auth does not appear to be configured to use SAS.

The systemd update is removing pam configurations.

Example:

zypper install systemd

The following NEW package is going to be installed:
 systemd-lang

The following 3 packages are going to be upgraded:
 systemd systemd-sysvinit udev

You can see when it's upgrading systemd it gets into the PAM configurations:

Installing: systemd-246.16-150300.7.39.1.x86_64

Additional rpm output:
warning: /etc/pam.d/systemd-user created as /etc/pam.d/systemd-user.rpmnew
common-auth-pc: Unknown module pam_vas3.so, ignored!
common-auth-pc: Unknown module pam_vas3.so, ignored!

Immediately after this, the PAM files are altered.

For example common-auth-pc goes from this:

auth    required        pam_env.so
auth    sufficient      pam_vas3.so create_homedir get_nonvas_pass
auth    requisite       pam_vas3.so echo_return
auth    required        pam_unix.so try_first_pass use_first_pass
account required        pam_warn.so
account required        pam_deny.so
password        required        pam_warn.so
password        required        pam_deny.so
session required        pam_warn.so
session required        pam_deny.so

To this:

auth    required        pam_env.so
auth    required        pam_unix.so     try_first_pass

Run the following command to restore the Safeguard Authentication Services PAM configurations:

/opt/quest/bin/vastool configure pam
