Thanks for getting back. Noticing a couple of things about your pasted output:
- Did you run the first set of commands in a root session? This is necessary 
because the user needs to be able to read the 
`/var/run/adsys/krb5cc/$(hostname)` file. You can confirm this by trying to 
`cat` the file - it shouldn't give you a Permission denied error.

- The export command looks a bit wrong, we need
`KRB5CCNAME=/var/run/adsys/krb5cc/$(hostname)` since `hostname` is a
shell command. You can confirm that the variable is set correctly by
running klist (provided by the krb5-user package). See an example below:

root@jammy-337515ec:~# export KRB5CCNAME=/var/run/adsys/krb5cc/jammy-337515ec
root@jammy-337515ec:~# klist
Ticket cache: FILE:/var/run/adsys/krb5cc/jammy-337515ec
Default principal: JAMMY-337515EC$@DOMAIN.COM

- You ran `smbclient` with sudo - unfortunately sudo does not preserve
environment variables which is why the KRB5CCNAME value defaults to
`FILE:/tmp/krb5cc_0` (as seen from the second command logs). This is why
I suggested running everything as root. Or, pass the -E flag to sudo in
order to preserve environment variables.


If there's no file at `/var/run/adsys/krb5cc/$(hostname)`, please run `adsysctl 
update -m` as root and it should be created (even if the command fails).

Thanks for your patience, and let me know how this goes

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 
client internal error: NT_STATUS_INVALID_PARAMETER
  Failed to open session: (1, 'LDAP client internal error: 
NT_STATUS_INVALID_PARAMETER').

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

  Full info 22.04 (-vvvv verbose):

  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.
