New comment by kruceter on void-packages repository https://github.com/void-linux/void-packages/pull/40846#issuecomment-1416555297 Comment: Thank you for sharing. Reproduced it clearly: ``` (2023-02-04 3:08:57): [pam] [sss_load_nss_symbols] (0x0010): Unable to load libnss_files.so.2 module, error: Error loading shared library libnss_files.so.2: No such file or directory ``` It seems THEY hardcoded this library in https://github.com/SSSD/sssd/blob/master/src/util/nss_dl_load.c. ``` libpath = talloc_asprintf(NULL, "libnss_%s.so.2", libname); ``` Just double-checked and it seems Alpine's sssd does not link against `nss` at all. From what I see in the provided configuration, nss is the vital module. Yes, something else may work on musl, but upstream clearly hardcodes to use glibc and may possibly create more problems in future.
