Tech Trek: A Software Engineer's Guide to Code and Beyond

Today, I have encountered one interesting tool in Shibboleth IdP which will check the resolver, filters and also the metadata so that you can know exactly what will happen in any given situation without starting the IdP. J As a developer, I would say it’s a great tool as you don’t have to restart your IdP again and again after every changes. The name of the tool is (Attribute Authority, Command Line Interface) ACCLI which is located in the IDP_HOME/bin directory and is called aacli.sh or aacli.bat. How it works? Make sure, you have set IDP_HOME to your system environment variable. To check what all attribute it will return for userId SysAdmin and Service Provider EntityId “https://domain.waheedtechblog.com/shibboleth”) aacli.bat --configDir=C:\idp\conf\ --principal=SysAdmin --requester=https://domain1.com/Shibboleth Please check here for detail information.

Scenario: I have an Apache Server(SSL enabled) and tomcat running on my machine and there is one application (app1) hosted on tomcat which is only accessible from Apache Server. You cannot access it directly from tomcat. Now you want to access app1 using multiple domains i.e. domain1.waheedtechblog.com annd domain2.waheedtechblog.com should point to the same application which is hosted on tomcat. (I want to implement different Authentication mechanism based on different domains) Solution: The above case can be achieved using NameBased VirtualHosts and SSL. First you need to uncomment following lines form ${apache}/conf/httpd.conf file LoadModule ssl_module modules/mod_ssl.so LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_ajp_module modules/mod_proxy_ajp.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule proxy_http_module modules/mod_proxy_http.so Include conf/extra/httpd-ssl.conf then goto ${apache}/conf/extra/httpd-ssl.co...

I have already discussed how to generate SSL certificate using keytool over here . In this article, I am going to explain how can you achieved the same thing using OpenSSL tool. The three differnet files that I am going to generate i.e. : waheedtechblog.key waheedtechblog.csr waheedtechblog.crt Generate Private key : waheedtechblog.key openssl genrsa -des3 -out waheedtechblog.key 1024 Generate a Certificate Signing Request (CSR) Using above generated key file, We will now create the CSR file openssl req -new -key waheedtechblog.key -out waheedtechblog.csr Generate a Self-Signed SSL Certificate openssl x509 -req -days 365 -in waheedtechblog.csr -signkey waheedtechblog.key -out waheedtechblog.crt These file can be used to enable SSL in Apache Server. Sometime, we need to remove passphrase to run key in Apache Server, if you get such issue while enabling SSL in Apache Server then run following command to remove p...
