Hi there,
Samba Version 4.17.12-Debian
I am having to constantly restart winbind and smbd in order for my client
machines to print.
Every 5 or so minutes, the printers from this print server appear as
"Server offline" in Windows. If I restart smbd and winbind at the same
time, they come back for a bit, and everyone can print as per normal.
I have seen the bug report to delete printer_list.tdb, and done that yesterday.
In the log.rpcd_spoolss file, I see entries such as this below:
[2023/10/26 09:27:21, 0]
../../librpc/rpc/dcesrv_handles.c:130(dcesrv_handle_lookup)
dcesrv_handle_lookup: Attempt to use invalid sid

The SIDs are valid, and point to a logged on user and their workstation.
The winbindd.log file has thousands of entries like these:
[2023/10/26 09:28:58.028357, 1]
