ruby 操作 ldap 的 bind 方法错误

sven — Tue, 11 Mar 2014 18:29:37 +0800

#!/usr/bin/ruby -w
require  'ldap'

$HOST =    '192.168.18.65'
$PORT =    LDAP::LDAP_PORT

base = 'ou=users,dc=case,dc=org'
scope = LDAP::LDAP_SCOPE_SUBTREE
filter = '(&(objectClass=caseAccount)(uid=case.lu@case.org))'
attrs = ['cn']


conn = LDAP::Conn.new($HOST, $PORT)
conn.bind('cn=Manager,dc=case,dc=org','case',LDAP::LDAP_AUTH_SIMPLE)

conn.perror("bind")
begin
  conn.search(base, scope, filter ,attrs) { |entry|
     # print distinguished name
     p entry.dn
     # print all attribute names
     p entry.attrs
     # print values of attribute 'sn'
     p entry.vals('cn')
     # print entry as Hash
     p entry.to_hash
  }

rescue LDAP::ResultError
  conn.perror("search")
  exit
end
conn.perror("search")
conn.unbind


报了如下错误就是bind方法那行。
deal_ldap.rb:14:in `bind': Protocol error (LDAP::ResultError)
    from deal_ldap.rb:14:in `<main>'
报错了，不知道为啥。找不到原因，bind方法应该就是这样的吧？？或者有好的方法吗？？先谢谢啦。

关于 backup 执行报错。

backup perform --trigger my_backup

这样是好的

sudo backup perform --trigger my_backup

这样就报错如下

/usr/local/lib/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find backup (>= 0) amongst [] (Gem::LoadError)
    from /usr/local/lib/ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec'
    from /usr/local/lib/ruby/1.9.1/rubygems.rb:1231:in `gem'
    from /usr/local/bin/backup:22:in `<main>'

我知道 gem 不支持 ruby-1.9.1 我把 1.9.1 都删掉了，可是还是会这样用 rvm remove 删掉的。。为什么会这样？？求解？
