its about redhat linux version 6.0 and passwd rpm version 0.58. the trouble is that passwd command returns segmentation fault. i am using pam version 0.66 and glibc version 2.1.3. verifying glibc version with rpm gives following 2 missing files /usr/share/locale/ru_Ru/LC_COLLATE /usr/share/locale/ru_Ru/LC_CTYPE i don't know these files have anything to do with the problem. i am also running openssl. i tried removing and installing passwd rpm, it reports a conflict with /usr/man/man1/passwd.1 file of openssl and has to be force- installed. i do need openssl even if it conflicts with the present problem.
