Hi,

I'm trying to authorize users in different AD's (2003 and 2008), but I
keep running into an error I can't find any thing on when I google it.

For the purpose of the testing I have set the following in the ldap
section: require_cert

Freeradius tries to connect to the ldap server (2008), the connection
fails and I get the following debug output.

This is a logging bug in FreeRADIUS; the code seems to have been copy & pasted. It *is* setting the randfile option, but it's logging the wrong thing (key file). It can be ignored.

Well that's a new one on me.

Which version of FreeRADIUS are you using, on which OS? Which LDAP libraries are you linking against?

I'm guessing you're on a RedHat based system, judging from the fact the LDAP libraries seem to be using Mozilla NSS rather than OpenSSL under the hood?

Where did "server.crt" come from? I presume it's a copy of the LDAP server cert, signed by the CA in "ca.pem"? Do you need it? You can probably just give the CA cert, for a connection to an LDAP server.
