I’m new to RT and Perl, but with some good skills with Linux.
Can’t call method “as_string” on an undefined value at/opt/rt3/local/plugi=
ns/RT-Authen-ExternalAuth/lib/RT/Authen/ExternalAuth/LDAP.pmline 100
’group’ =3D> ‘svn Users’,
‘group_attr’ =3D> ‘svn Users’,

I doubt the group and the group_attr are both named ‘svn Users’ and
you’re generating invalid group search syntax.
