Error when SQLAuthlogic authenticator has no encryptor_options

[bitaxis]

I have configured rubycas-server to use the Authlogic authenticator. I found that in config.yml, if I don't specify any encryptor_options in the authenticator section, then CASServer::Authenticators::SQLAuthlogic#validate errors out with the following:

NoMethodError - undefined method `each' for nil:NilClass:
/home/bitaxis/.rvm/gems/ruby-1.9.2-p290/gems/rubycas-server-1.0.1/lib/casserver/authenticators/sql_authlogic.rb:69:in `validate'
/home/bitaxis/.rvm/gems/ruby-1.9.2-p290/gems/rubycas-server-1.0.1/lib/casserver/server.rb:444:in `block (2 levels) in <class:Server>'
/home/bitaxis/.rvm/gems/ruby-1.9.2-p290/gems/rubycas-server-1.0.1/lib/casserver/server.rb:436:in `each'
/home/bitaxis/.rvm/gems/ruby-1.9.2-p290/gems/rubycas-server-1.0.1/lib/casserver/server.rb:436:in `block in <class:Server>'

The reason is simple, as @options[:encryptor_options] evaluates to nil when no encryptor_options are specified.

One fix is modifying line 69 to be as follows:

(@options[:encryptor_options] || []).each do |name, value|   

I've tested this fix locally, and it works fine.
