Oops,
I've missed something.
What i meant is if it is possible to have them working at the same time.
I have tried the Database authentication and the LDAP authentication. They both work perfectly, but i can't put them working at the same time.
This article
http://doc.otrs.org/3.0/en/html/auth-backends.html refers how to configure different authentication methods, but it doesnt explain on how to have them working at the same time.
When I enable both these authentication methods on the Config.pm file, what happens is that just one of the methods will work
I've managed to do something similar with the Customers (it is very easy to setup different customer data sources) but I haven't been able to do the same with the agents so far.
Thanks in advance,
Pedro
