Hi, I have a problem with linking the pam with an external library. The problem is I am linking the pam with libhlgpl.so.1 as following gcc -shared -Xlinker -x -o pam_stack.so dynamic/pam_stack.so -lhlgpl Everything works fine. The problem happens at runtime. When pam_stack get called, it try to load pam_stack and it fails with error message " PAM adding faulty module: /lib/security/pam_stack.so proftpd[11470] Feb 28 12:57:27 PAM [dlerror: libhlgpl.so: cannot load shared object file: No such file or directory] proftpd[11470] Feb 28 12:57:27 PAM unable to dlopen(/lib/security/pam_stack.so) " Anyone have any idea why this happens? and how to link the pam with external library? Thank alot Luyen Tran _______________________________________________ Pam-list@redhat.com https://listman.redhat.com/mailman/listinfo/pam-list
