What steps will reproduce the problem?
1. Freebsd 9.x or 10.x install
2. Install openvpn-auth-ldap package (version 2.0.3)
3. configure to use it in ldap.conf:
plugin /usr/local/lib/openvpn-auth-ldap.so "/usr/local/etc/openvpn/ldap.conf"

What is the expected output? What do you see instead?
Not staring openvpn, because in log (with verb 11):

What version of the product are you using? On what operating system?
Freebsd 9 or 10, openvpn-auth-ldap version 

Please provide any additional information below.
Earlier the same config on Freebsd 8 it worked, others see the same, like:

Apparently the real problem on newer FreeBSD releases (9.x and newer) is that 
newer compiler versions have also moved on to a "lighter", near-trivial, 
"Object" base class that no longer provides static/class methods such as 
+alloc.  

IOW, it seems necessary to either implement the missing methods in a 
project-specific base class that, or to port auth-ldap to some framework 
(gnustep-base perhaps?) that provides the necessary +alloc and other methods.

I cannot do that due to a current lack of ObjC-fu.

This sucks and I hope someone can figure out how to fix it soon.  Got all the 
way through an update on my firewall and found out my 2fa openvpn setup was now 
broken.  As a workaround I whipped up this simple perl script to do LDAP auth 
with.  If anyone else is stuck I hope this can tide you over until the compiled 
version is fixed.
