Hello.
I have setup a test FreeIPA server and client, CentOS 8.3, very minimal, exactly as the
documentation. I can successfully mount a Samba shared from ipaclient on MacOS, the
first access. But any subsequent share mounting fails until winbind is restarted. Please
see this screen capture which explicitly shows the issue.

This program will set up the IPA Server.
Version 4.8.7
This includes:
* Configure a stand-alone CA (dogtag) for certificate management
* Configure the NTP client (chronyd)
* Create and configure an instance of Directory Server
* Create and configure a Kerberos Key Distribution Center (KDC)
* Configure Apache (httpd)
* Configure DNS (bind)
* Configure the KDC to enable PKINIT
To accept the default shown in brackets, press the Enter key.
Enter the fully qualified domain name of the computer
on which you're setting up server software. Using the form
<hostname>.<domainname>
Example: master.example.com.
Server host name [freeipa01.ipa.instinctual.studio]:
Warning: skipping DNS resolution of host freeipa01.ipa.instinctual.studio
The domain name has been determined based on the host name.
Please confirm the domain name [ipa.instinctual.studio]:
The kerberos protocol requires a Realm name to be defined.
This is typically the domain name converted to uppercase.
Please provide a realm name [IPA.INSTINCTUAL.STUDIO]:
Certain directory server operations require an administrative user.
This user is referred to as the Directory Manager and has full access
to the Directory for system management tasks and will be added to the
instance of directory server created for IPA.
The password must be at least 8 characters long.
Directory Manager password:

The ipa-client-install command was successful
==============================================================================
Setup complete
Next steps:
1. You must make sure these network ports are open:
TCP Ports:
* 80, 443: HTTP/HTTPS
* 389, 636: LDAP/LDAPS
* 88, 464: kerberos
* 53: bind
UDP Ports:
* 88, 464: kerberos
* 53: bind
* 123: ntp
2. You can now obtain a kerberos ticket using the command: 'kinit admin'
This ticket will allow you to use the IPA tools (e.g., ipa user-add)
and the web user interface.
Be sure to back up the CA certificates stored in /root/cacert.p12
These files are required to create replicas. The password for these
files is the Directory Manager password
