Cisco offers a free version of TACACS+ that you can download. However, please note that it is not a fully supported version. In fact, Cisco seldom updates the free TACACS+ daemon and it lacks several of the advanced features of commercially available TACACS+ software. Furthermore, Cisco warns that this free software comes with no warranty or support.
With this in mind however, the free TACACS+ software is useful for testing, lab environments, or even small installations. You will find that the free Unix version is fully functional and provides an excellent range of features. In fact, all of the AAA accounting log files in this chapter were captured using Cisco's free TACACS+ software.
Please follow the instructions that Cisco provides with the software to extract, compile, and install the TACACS+ server software. Recipe 4.9 includes some sample configuration files.
