Hi all, Ruby 1.8.6 Windows XP Pro ruby-net-ldap 0.0.4 I’m getting a strange error when I try this simple script, where LDAP\_SERVER is a 3rd party ldap server: ldap = Net::LDAP.new(:host =\> LDAP\_SERVER, :port =\> 9999) ldap.bind(:dn =\> ‘cn=Admin’, :password =\> ‘xxx’) ldap.unbind /lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ber.rb:117:in `read_ber': unsupported object type: class=contextspecific, encoding=primitive, tag=7 (Net::BER::BerError) from C:/ruby/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ ber.rb:112:in`read\_ber’ from C:/ruby/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ ldap.rb:1104:in `bind' from C:/ruby/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.0.4/lib/net/ ldap.rb:701:in`bind’ from user.rb:26 Any ideas? Thanks, Dan ---

If that doesn’t solve the problem, then I’ll look into it more closely for you. ---

All I see under trunk, however, is a bunch of CVSROOT files. What am I supposed to grab? The stuff under the experimental\_netldap branch? Thanks, Dan ---

Yes, sorry about that, it’s under branches/experimental\_netldap. I came into that project in midstream and didn’t want to disturb the existing code, so I added that branch. I know I supported some more of the BER types when I added SNMP support to that library a few months back, so I’m hopeful this will solve your problem. ---

Did I botch the install somehow? I think it’s a code problem. I added this line at 1231: meth ||= :simple But now I get this error: user.rb:28: undefined method `unbind’ for #Net::LDAP:0x2760280 (NoMethodError) I think there’s something fundamentally broken with ldap.rb now, but I couldn’t tell you what it is.

Ok. Now I’m seeing this (same code as before): C:\Documents and Settings\djberge\workspace\ruby-cramer\lib \cramer\>ruby user.rb C:/ruby/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.1.0/lib/net/ldap.rb: 1238:in `bind': unsupported auth method () (Net::LDAP ::LdapError) from C:/ruby/lib/ruby/gems/1.8/gems/ruby-net-ldap-0.1.0/lib/ net/ldap.rb:730:in `bind’ from user.rb:26 Any ideas? Did I botch the install somehow? Regards, Dan ---

But now I get this: user.rb:28: undefined method `unbind’ for #Net::LDAP:0x2760258 (NoMethodError) Strange. Any ideas? Regards, Dan ---

I was a little mystified that you were having so much trouble with a simple operation that is known to work well, so I went back and checked the rdoc for Net::LDAP#bind. This is a method that is usually called implicitly by the library, such as when user code requests a search against the LDAP directory. However, there is an example in the documentation of how you can successfully use #bind without parameters. I just added an additional example to cover the case you used (in which credentials are passed to #bind as arguments).
