Hello, In order to store users in alternate passwd, shadow and group files I have written some patches over Linux PAM 1.0.2 and an NSS module. With these packages one can store the passwd, shadow and group files for the cluster users over GFS/OCFS2/Lustre/etc. We have been using such a setup for more than half a year in production. If somebody is interested in, the patches, sources and the installation, configuration descriptions are available at http://www.kfki.hu/~kadlec/sw/cluster/ The PAM patches fix some bugs and add new features too: - By default Linux PAM links with libxcrypt instead of libcrypt from glibc. However the source files include crypt.h and not xcrypt.h, thus the functions from libcrypt is used in spite of linking with libxcrypt. - Simplify source when a function is used both in the pam_unix module and in the helper binaries. - Linux PAM can check blowfish encrypted passwords (if the crypto library supports it), however it did not support new passwords to be encrypted by blowfish. One patch adds full blowfish support (and "blowfish" keyword) to pam_unix. - @include keyword support (for Debian/Ubuntu).
