Fix Microsoft WinRM provider import failure under lowest dependencies#69333
Merged
Conversation
pywinrm imports `spnego.ContextProxy`, which pyspnego only exposes from version 0.4.0 onwards. The winrm provider only declared `pywinrm>=0.5.0` and left pyspnego unbounded, so lowest-dependency resolution selected a pre-0.4.0 pyspnego and the provider failed at import time with `module 'spnego' has no attribute 'ContextProxy'`, breaking the LowestDeps CI job. Flooring pyspnego directly keeps the lowest-dependency resolution on a version that actually provides the attribute pywinrm needs.

The Microsoft WinRM provider declared only
pywinrm>=0.5.0and leftpyspnego(a transitive dependency of pywinrm) unbounded.
pywinrmimportsspnego.ContextProxy, whichpyspnegoonly exposes from version0.4.0onwards, so lowest-dependency resolution selected a pre-
0.4.0pyspnegoandthe provider failed at import time with
module 'spnego' has no attribute 'ContextProxy'— breaking theLowestDepsproviders CI job.
Flooring
pyspnego>=0.4.0directly in the provider keeps lowest-dependencyresolution on a version that actually provides the attribute
pywinrmneeds.The gap is pre-existing on
main(surfaced by the failingLowestDepsshard onPR #64643, which is unrelated to that PR's Samba change).
