Hi everyone!
I want to authenticate to my Switch via Tacacs+. It runs fine as long as I define Users and passwords in the /etc/tac-plus/tacacs.conf. But when I try to authenticate against a MySQL DB or the /etc/passwd file, authentication fails.
With the config below, I'm able to login with username fred. In MySQL DB a user 'test' with password ENCRYPT('test') is correctly set up. I use the DB skel which comes with tacacs+ (in Debian it's in /usr/share/docs/tac-plus, manual from http://www.gazi.edu.tr/tacacs/docs/tacacs_db.txt)
---------------------
My tacacs+ config:
# /etc/tac-plus/tacacs.conf
### TACACS+ Config
# Auth-Key
key = some_key
#default authentication = file /etc/passwd
default authentication = db mysql://user:password@localhost/tacacs/auth?usern&passwd
accounting file = /var/log/tac-plus/account.log
###### USER ######
user = DEFAULT {
default service = permit
}
#user = DEFAULT {
# service = ppp
# protocol = ip {
# }
#}
# Enable-User
#user = $enable$ {
# login = cleartext test
#}
user = fred {
default service = permit
login = cleartext fred_pw
}

It would be great if someone could help.
