Hi, I have looked but cannot find a solution to this !, here goes I am installing PAM onto a newly compiled linux variant I am using glibc 2.2.5 GCC 3.0.4 I am using util-linux-2.11q for login etc... PAM compiles fine and installs fine (besides some .so symlink stuff ups) util-linux compiles and installs fine but when i try to login in i get this in my logs Apr 19 11:48:56 stampy login: PAM unable to dlopen(/lib/security/pam_permit.so) Apr 19 11:48:56 stampy login: PAM [dlerror: /lib/security/pam_permit.so: undefined symbol: pam_get_user] Apr 19 11:48:56 stampy login: PAM adding faulty module: /lib/security/pam_permit.so Apr 19 11:48:56 stampy login: PAM unable to dlopen(/lib/security/pam_unix.so) Apr 19 11:48:56 stampy login: PAM [dlerror: /lib/security/pam_unix.so: undefined symbol: pam_get_user] Apr 19 11:48:56 stampy login: PAM adding faulty module: /lib/security/pam_unix.so Apr 19 11:48:56 stampy login: FAILED LOGIN SESSION FROM (null) FOR root, Module is unknown Apr 19 11:48:58 stampy login: PAM unable to dlopen(/lib/security/pam_permit.so) Apr 19 11:48:58 stampy login: PAM [dlerror: /lib/security/pam_permit.so: undefined symbol: pam_get_user] Apr 19 11:48:58 stampy login: PAM adding faulty module: /lib/security/pam_permit.so Apr 19 11:48:58 stampy login: PAM unable to dlopen(/lib/security/pam_unix.so) Apr 19 11:48:58 stampy login: PAM [dlerror: /lib/security/pam_unix.so: undefined symbol: pam_get_user] Apr 19 11:48:58 stampy login: PAM adding faulty module: /lib/security/pam_unix.so Apr 19 11:48:58 stampy login: FAILED LOGIN SESSION FROM (null) FOR root, Module is unknown my /etc/pam.d setup is fine login looks for pam_permit.so and my other looks for pam_unix.so Can somebody please help me because this is very frustrating!
