Subject: [users@httpd] pwauth won't compile with PAM support
Dear,
I would like to add authentication (against the unix shadow file) to my
apache web server. But with the ability to lockout a user after 5 incorrect
attempts (in order to lockout script-kiddies / password-trial-programs).
For what I 've read about this on the web. This combination should work :
- Red Hat Enterprise linux 3 (3.2.3-20)
- Kernel 2.4.21-4.EL
- apache 2.0.46-25.ent
- mod_auth_external-2.2.11
- pwauth-2.3.2
- pam-0.75-51
at least : I 'm trying to get this working.
Everything went fine, until the moment I try to compile pwauth with PAM
support
Before compiling pwauth, I changed the config.h to use PAM :
< /* #define SHADOW_SUN /* Linux, Solaris, IRIX */
< #define PAM /* Linux PAM or OpenPAM*/
< /* #define NOLOGIN_FILE "/etc/nologin" /**/
< /* #define MIN_NOLOGIN_UID 1 /**/
< #define SERVER_UIDS 48 /* user "apache" */
Compilation of all pwauth-c-files goes fine, but the linker gives this
error :
gcc -o pwauth -g main.o auth_aix.o auth_bsd.o auth_hpux.o \
auth_mdw.o auth_openbsd.o auth_pam.o auth_sun.o fail_log.o \
lastlog.o nologin.o snooze.o -lcrypt
auth_pam.o(.text+0x1f8): In function `check_auth':
/root/download/mod_auth/pwauth-2.3.2/auth_pam.c:174: undefined reference

/auth_pam.c:177: undefined reference to `pam_authenticate'

auth_pam.o(.text+0x241):/root/download/mod_auth/pwauth-2.3.2
/auth_pam.c:182: undefined reference to `pam_end'
collect2: ld returned 1 exit status
make: *** [pwauth] Error 1
Two questions about this :
1) What am I doing wrong / What am I missing .... to make this program
compile without errors ???
2) Am I using the right programs to achive my goal (ie: password
authentication against simple user-database with the ability to lockout
password-trial-programs) ??
Thanks in Advance,
Koen.
