Omniauth 2.0 support?

[duffyjp]

I'm looking to upgrade omniauth to 2.0, but the gemspec for this strategy is major version locked at 1.

omniauth-ldap/omniauth-ldap.gemspec

Line 12 in 3242f85

gem.add_runtime_dependency 'omniauth', '~> 1.8.1'

Are there internal plans to update omniauth-ldap, or are you looking for a champion?
