Quick test case, to be used in the sru template later on:
sudo apt update
sudo apt install sssd winbind
create this /etc/samba/smb.conf:
[global]
log file = /var/log/samba/log.%m
map to guest = Bad User
max log size = 1000
panic action = /usr/share/samba/panic-action %d
server role = standalone server
server string = %h server (Samba, Ubuntu)
syslog = 0
idmap config * : backend = sss
idmap config * : range = 200000-2147483647
sudo systemctl restart winbind
Run this command to trigger the loading of the sss module. It will fail
because, among other reasons, this machine is not part of a domain, but that's
fine:
# wbinfo --allocate-uid
failed to call wbcAllocateUid: WBC_ERR_DOMAIN_NOT_FOUND
Could not allocate a uid
Now /var/log/samba/log.winbindd-idmap will contain:
[2019/06/27 17:45:18.420790, 0]
../source3/winbindd/idmap.c:328(smb_register_idmap)
Failed to register idmap module.
The module was compiled against SMB_IDMAP_INTERFACE_VERSION 5,
current SMB_IDMAP_INTERFACE_VERSION is 6.
Please recompile against the current version of samba!
[2019/06/27 17:45:18.421110, 0]
../lib/util/modules.c:173(load_module_absolute_path)
load_module_absolute_path: Module
'/usr/lib/x86_64-linux-gnu/samba/idmap/sss.so' initialization failed: {Wrong
Type} There is a mismatch between the type of object that is required by the
requested operation and the type of object that is specified in the request.
This confirms the bug.
