Hey, Thnx for the support, and indeed i use linux *off course* ! I do everything on debian these days. I checked for PAM internet on the official site: http://www.kernel.org/pub/linux/libs/pam/ I have PAM installed (or else my linux wouldn't work) and i installed the newer version also. But it is still not working, where can i find those devel packages ? I looked on: http://www.kernel.org/pub/linux/libs/pam/pre/ (there are all the pam packeges) But what exactly do i have to install ? I need winbind for windows authentication testing. I am not so familiar with the devel packages, i have PAM and it's working and don't know lot's more about other devels. I checked dselect from debian and there i can see that: Libpam0g-dev and these should be the development files for PAM, and it is installed. > configure:14172: checking whether struct passwd has pw_age > configure:14224: checking for poptGetContext in -lpopt > configure:14267: checking whether to use included popt > configure:14282: checking configure summary > configure:14291: gcc -o conftest -O -D_LARGEFILE64_SOURCE > -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE conftest.c -ldl -lnsl -lpam 1>&5 > /usr/bin/ld: cannot find -lpam > collect2: ld returned 1 exit status > configure: failed program was: > #line 14287 "configure" > #include "confdefs.h" > #include "./tests/summary.c" _______________________________________________ Pam-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/pam-list
