Description of problem:

new/fresh f33 installation as of nov 29. not an in-place upgrade.
since dec 02 or 03, "dnf update" has reported problems with updating samba packages.
recommendation from dnf to add --best --allowerasing does not improve the situation.
all the named problems appear to revolve around samba credentials.
other packages continue to update without incident.

Version-Release number of selected component (if applicable):

libsmbclient-4.13.2-1.fc33.x86_64.rpm
libwbclient-4.13.2-1.fc33.x86_64.rpm
samba-4.13.2-1.fc33.x86_64.rpm
and several of the related samba-* packages, though not all are involved

How reproducible:

every time i attempt dnf update.

Steps to Reproduce:
1. have samba installed
2. dnf update

Actual results:

# dnf update

Expected results:

normal update success.

Additional info:

there were other packages installed that also showed problems, which i removed in the effort to get to the smallest set showing conflict.
the set above apparently can't be reduced further because attempting to remove them causes conflict over removing protected package gnome-shell.
others now removed involved included libavif, xmms2* (including some from rpmfusion, which is why i removed packages to reduce set until the set was contained with fedora and updates), efl, and darktable.
