Ldap implementation

Got RT up and running and then decided to try implementing our corporate
ldap into it… Seems I must have something configured wrong.
I added to the RT_SiteConfig.pm:
$LDAPExternalAuth = 1;

Once I did that, I began erroring out with:

error: could not find component for path ‘/l’

context: …
92: % }

94: <&|/l, “”.$session{‘CurrentUser’}->Name."" &>Logged in as
95: % } else {
96: <&|/l&>Not logged in.</&>
97: % }

code stack: /opt/rt3/share/html/Elements/Header:96

I took that out and it is still erroring with this…

Any ideas would be greatly appreciated.
