Hi, while compile passwd slapd-modules, I've got error on Radius compilation. gcc -DOPENLDAP_FD_SETSIZE=4096 -O2 -g -DSLAP_SCHEMA_EXPOSE -g -O2 -I/usr/kerberos/include -I../../../include -I../../../include -I../../../servers/slapd -c radius.c -fPIC -DPIC -o .libs/radius.o radius.c:27:20: fatal error: radlib.h: No such file or directory #include <radlib.h> I've searched which package could provide the radlib file but I didn't found it. Please confirm which package should be used .. or link to the source.. I'm on CentOS
