Thanks for reviewing.

I used samba under debian stretch last December, and
confirmed current code worked without the problem.

Recently, I have upgraded the server OS from stretch
to bullseye, and noticed this problem.

Perhaps, samba version and its protocol version may be
related.

My samba version is: Version 4.13.13-Debian

This also happens with shared folder under Windows 10
in my environment.

Win10 version is:
Microsoft Windows [Version 10.0.19044.1466]

The reproducible steps are as follows.

$ net use z: '\\server\sharedname'
The command completed successfully.

$ cd /cygdrive/z
/cygdrive/z: Too many levels of symbolic links.
$
