Dear All
While executing TLS enabled Kamailio proxy (3.1.5), getting below error.
* 0(15895) INFO: tls [tls_domain.c:227]: TLSs<default>: verify_depth=9

I performed below steps to compile and install.
1. I had a working Kamailio-3.1.5 code base without TLS
2. Downloaded latest openssl source code
3. Compiled and generated libssl.a and libcrypto.a
4. Next, I recompiled kamailio proxy, compilation did not go through. I had
to modify Makefile in modules/tls module, added path for openssl/bio.h and
path for libssl.a
5. Then executed make all clean and make all include_modules=tls , this
time compilation succeeded
6. Next I did make install
7. Generated certificates using openssl library that comes by default with
ubuntu 10.04 lte
8. Added below entries in kamailio.cfg
#!define WITH_TLS
#!ifdef WITH_TLS
loadmodule "tls.so"
modparam("tls", "config", "/usr/local/etc/kamailio/tls.cfg")
modparam("tls", "private_key", "/etc/certs/localb2bua.com/key.pem")
modparam("tls", "certificate", "/etc/certs/localb2bua.com/cert.pem")
modparam("tls", "ca_list", "/etc/certs/demoCA/cert.pem")
enable_tls=yes
#!endif
9. Then I tried running kamailio proxy
It complained not getting tls.so and tls.cfg
Copied these files from modules/tls to /usr/local/etc/kamailio/ path
10. Then I was able to run Kamailio proxy and got the errors pasted at top
of email (* Unable to load certificate file
'./modules/tls/ser-selfsigned.pem')
*
Please guide me what should I do to avoid this error.
Thanks a lot.
