Since Samba 4.18 the removal of a symlink, which points to a directory, fails with NT_STATUS_OBJECT_NAME_NOT_FOUND. With 4.17.12 it's working.

The share definition on a basic fileserver is:
[share]
        path = /share
        read only = No

The content on the filesystem looks like:
root@dm9:~# ls -l /share
total 4
drwxr-xr-x 2 TEMP\bb TEMP\domain users 4096 Jan 30 20:36 destdir
lrwxrwxrwx 1 TEMP\bb TEMP\domain users    7 Jan 30 20:05 link_to_destdir -> destdir

Failing command via smbclient:
smb: \> ls
  .                                   D        0  Tue Jan 30 20:53:18 2024
  ..                                  D        0  Tue Jan 30 20:53:18 2024
  destdir                             D        0  Tue Jan 30 20:36:42 2024
  link_to_destdir                     D        0  Tue Jan 30 20:36:42 2024

smb: \> rmdir link_to_destdir
NT_STATUS_OBJECT_NAME_NOT_FOUND removing remote directory file \link_to_destdir

The attached logfile line 3504 shows that the smbd tries to chdir "share" instead of "/share" which fails with "No such file or directory". strace shows the same:
chdir("share")                          = -1 ENOENT (No such file or directory)

The issue is the same if the files are not placed in the share root.
Renaming the symlink is working. Symlinks to files can be removed successfully.
