Test failure in samba.tests.blackbox.smbcacls_basic(DFS)

[Joseph Sutton]

I noticed this failure occurring with the samba-no-opath2 job on GitLab
CI, after rebasing seemingly unrelated changes onto master.

I'm not sure exactly what caused this failure, but I'm reporting it here
in case this is an issue that could warrant further investigation.
