Centos 6.4/6.5 and Tacacs+


I have been given the task of upgrading our company servers from Rpath to Centos 6.5. We use Tacacs authentication that was packaged from Rpath in our OS baselines. Well I just downloaded Centos 6.5 Min and now I need to configure these client servers to authenticate via Tacacs. Where do I start?

I haven't seen any config files on the Rpath boxes that would show any form of configuration or key storage. These boxes must talk through Mysql or something for authentication.

Its looking like I might have to start these Centos boxes from scratch but I am not that savvy on Tacacs. Hopefully someone here is.

Not sure if this is much help, but on CentOS there is a configuration file for TACACS+ located at:

/etc/tac_plus.conf

If you have to start from scratch on the CentOS boxes the following gives a step-by-step guide:

Hope that helps or at least gets you on the right path.

I was using this at work. It helped a little bit but I guess my work environment is a little unique to be asking broad questions online. Thanks all for the help.

Question. How much of the tac_plus.conf file needs to be configured in order to get this server to talk? This server is a pass through device for pushing logs. I don't think we have any users and passwords saved in our old Rpath boxes but I can't find a config file similar to the Centos config file.

Seems like our authentication is run through Mysql so the stored users should be on the DB.

Found this in a config file on the Rpath box.

Would I just replace this in the tac_plus.conf file?

key mykey
default db = mysql://tacacs:tacacspassword@localhost/tacacs

Am I getting closer?

#If you like to use DB authentication
#default authentication = db “db_type://db_user:db_pass@db_hostname/db_name/db_table?name_field&pass_field
# db_type: mysql or null
# db_user: Database connect username
# db_pass: Database connection password
# db_hostname : Database hostname
# db_name : Database name
# db_table : authentication table name
# name_field and pass_field: Username and password field name at the db_table
