pam_python.so missing on Fedora

[Swiftb0y]

I'm using howdy from copr from @luyatshimbalanga and I was able to get it running with some minor patches but I've now discovered that fedora is simply missing pam_python.so I would appreciate if you could provide the missing pam_python library in the copr repo.

Linux distribution (if applicable): Fedora 32

Howdy version: 2.6.0

[luyatshimbalanga]

pam_python is already packaged on https://copr.fedorainfracloud.org/coprs/anaumov/pam-python/. What will be great is pam_python.so getting ported to python 3 instead. See the review process on https://bugzilla.redhat.com/show_bug.cgi?id=1641386

[Swiftb0y]

Thanks for your response. It would probably be wise to add that info to the fedora install instructions. Unfortunately, I struggle to enable that package. Do you know any workarounds?

sudo dnf copr enable anaumov/pam-python
[...]
Error: This repository does not have any builds yet so you cannot enable it now.

I ran into the same issue, but managed to get pam_python on fedora using the rpm sphere repo, however now instead I get an error about the dlib module not being found... despite installing manually / with pip2 / pip3, etc., which is strange considering it loads correctly from a python shell (both 2 and 3).

[Swiftb0y]

dlib is packaged with the copr repo. try installing python3-dlib from the repo instead of pip. when you do install dlib via pip from as your user, it will only be available for that user but howdy is run as root so it won't be able to find that version of dlib. consequently, you could also try installing dlib with sudo pip3 install dlib though the repo method seems to be preferred here since that guarantees that you are installing a compatible dlib version.

Tried installing python3-dlib from the repo, but now i get the error

No module named '_dlib_pybind11'

Can't import the dlib module, check the output of
pip3 show dlib

and they can't be found by the python shells despite being reported working by pip and being installed in the correct locations, /usr/lib64/python3.8/site-packages that is.

Having dlib installed using sudo pip3 install dlib is the way I had it set up before and results in howdy working however whenever a sign in is initiated I get the error

Traceback (most recent call last):
  File "/lib64/security/howdy/compare.py", line 18, in <module>
    import dlib
ModuleNotFoundError: No module named 'dlib'
Unknown error: 1

And again, it works in the python shell.

[Swiftb0y]

I've not been able to get to that stage yet so I can't help you with that. @boltgolt I would propose to deprecate the use of pam_python and instead use pam_exec (since that module seems much more widely available) in its place. Would you accept a PR for that?

[Swiftb0y]

I managed to get pam_python compiled with a couple of patches and now howdy works very well!

[LukaJankovic]

Which patches? Would you be willing to share the binary otherwise?

[principis]

@LukaJankovic I've created my own builds because of this (and other problems). Maybe it'll solve your problems https://copr.fedorainfracloud.org/coprs/principis/howdy/

@principis Thanks for your copr repo; do you plan to update it for Fedora 33? It's not installing for me on Fedora 33. I also tried compiling myself, and while howdy works for me, pam_python does not (I get a segmentation fault when trying to run it after compiling it myself). Any clues?

[principis]

@dbdorman I'll look into it

Edit: dlib should be packaged by fedora 33, so we can skip that part. I've compiled everything for fedora 33 over here. Fedora 33 is still in beta so I won't be installing it for a while.

Let me know if it works, I suspect it won't because you've compiled pam_python yourself, but it's worth a try. If it doesn't, can you try debugging it to figure out the problem?

Edit 2: I just tested it in a VM and it works fine.

[dbdorman]

@principis Thanks, I was able to install from your copr build, but still getting a segmentation fault when executing pam_python, so must be something with my system. I'll try debugging

[socketpair]

So what is the result of everything that ?

Could you please elaborate?

@principis https://github.com/rpmsphere/spec/pull/4 But I don't know how to add .patch there. I managed to compile it for Fedora39 (i.e. Python 3.12), but did not test yet.

@principis rpmsphere/spec#4 But I don't know how to add .patch there. I managed to compile it for Fedora39 (i.e. Python 3.12), but did not test yet.

I have no idea what you are trying to accomplish. I have packaged howdy here, which should work fine.
