freeRaidus-PAM:: .so file error

[krishna Mohan]

Hi,Am using freeradius 1.1.5 with pam configured.Wrote my pam application (mypam.so) file and trying to authenticate a user.No compilation errors while generating .so library.But getting "segmentation fault" error radiusd is executing a request.Btw,I have two setups; one with source compiled (fr1.1.5-tar.gz) and other rpm installed (fr1.1.5-i386.rpm). The generated .so is working perfectly with setup1.Earlier, got "PAM unable to resolve symbol: pam_sm_authenticate PAM unable to resolve symbol: pam_sm_setcred" error.  Added two dummy routines for both pam_sm_authenticate() and pam_sm_setcret(), to the pam auth module, so that they always return success.radiusd -X output:-------------------rad_recv: Access-Request packet from host 127.0.0.1:32768, id=19, length=46        User-Name = "john90"        User-Password = "password"  Processing the authorize section of radiusd.confmodcall: entering gr!
