Hey,
Unfortunately with Samba logs there's a lot of noise to filter out. I
compared one of your runs with my (successful) run and I noticed
something interesting.
We do a LDAP search to get the list of GPOs using the domain controller
exposed by SSSD via D-Bus. For you the DC is autoselected as
"n060adkhdc121". The list of GPOs is a list of URLs reported as
"smb://domain.com/SysVol/domain.com/Policies..." which doesn't contain
the DC name, only the domain name.
When we download the GPOs, libsmbclient will try to resolve a DC from
the domain, in your case it appears there are a lot of DCs advertised
(looking at the "Connecting to ... at port ..." prints). For some
reason, the DC selected by libsmbclient is "N060ADKAZ103" instead of the
DC reported by SSSD. Hence we end up with this error:
SPNEGO login failed: {Access Denied} A process has requested access to
an object but has not been granted those access rights.
I've pushed another build to the PPA mentioned above, where the GPO URLs
are rewritten to contain the hostname of the DC in addition to the
domain which will bypass the autoselect/discovery logic of libsmbclient
and reuse the server exposed by SSSD when downloading the GPO data. You
can install the package using the same steps from my previous comment.
Please let me know if it works for you.

Title:
Adsys can't fetch GPOs
Status in adsys package in Ubuntu:
Confirmed
Bug description:
Bad, maybe no understandable english ahead.
Can't find anything related to this on Github, Canonical Forums,
Reddit or StackOverflow.
On Ubuntu 22.04, I've followed the Wiki tutorial and verified all
steps on Integration Ubuntu Desktop whitepaper. Currently using SSSD
backend, I can log with Active Directory users however when adsys is
installed I can't fetch GPOs. In this version the error is:
ERROR Error from server: error while updating policy: can't get
policies for "ubuntu": can't download all gpos and assets: one or more
error while fetching GPOs and assets: can't download "ubuntuRoot":
can't check if ubuntuRoot needs refreshing: no GPT.INI file: cannot
open
smb://addc01.domain.com.br/SysVol/domain.com.br/Policies/{DF072E7E-6F2F-46D1-A90F-699415F72F2E}/GPT.INI:
invalid argument
It happens when using "adsysctl update -m" or "adsysctl update
usern...@domain.com.br /tmp/krb5c_getentId_randomdnumber" and just
"adsysctl update" too.
I've upgrade the machine to 22.10 and the error changed to:
ERROR Error from server: error while updating policy: can't get policies for
"ubuntu": failed to retrieve the list of GPO (exited with 1): exit status 1
Failed to bind - LDAP client internal error: NT_STATUS_INVALID_PARAMETER
Failed to connect to 'ldap://addc01.domain.com.br' with backend 'ldap': LDAP

After upgrade to 23.04 the error persist same as the above.

Additional info:
Domain Controller and machine are on the same subnet without firewall on any
level;
Domain Controller is a Windows Server 2019 updated to the last security
version;
Both machine and user are on the same OU with "no heritage" enabled and just
one policy added to permit usern...@domain.com.br to become root;
The info header directory is "/home/jzprates" on both logs because I've
collected them using the local account using "sudo adsysctl update -m -vvvv";
If I disable Adsys login on pam-auth-update, Ubuntu creates a homedir and
enter correctly with domain users.
