Subject: net ldap problem?

Hi!
I have server with Active Directory.
I wanted to do somethink like thet:

def changelogonhours(name,ldap)
    filtr = Net::LDAP::Filter.eq("cn",name)
    ldap.search(:base => "dc=example,dc=local", :filter => filtr){|ut|
  p ut[:dn]
  p ut[:logonhours]
  ut1,ut2 =  Marshal.dump(ut[:logonhours]).split("\032")
  ut1 = ut1 + "\032"
  ut2, ut3 = ut2.split("\006:")
  ut3 = "\006:" + ut3
  ut2a=[]
  (0..6).each{|g|
      ut2a[g] = ut2[g*3..g*3+2]
  }
  tmp=ut2a[1]
  (2..6).each{|g|
      ut2a[g-1]=ut2a[g]
  }
  ut2a[6]=tmp
  ut_new = ut1 + ut2a.join + ut3
 # here begins my problem
  ldap.replace_attribute ut[:dn], :logonhours, Marshal.load(ut_new)
  p ut[:logonhours]
    }
end

Ruby responds:

["CN=Tom Bombadil,OU=Users,DC=exmple,DC=local"]
["\300\377\017\000\000\000\000\000\000\000\000\b\000\000\004\000\000\001\000\000\000"]

If you have some idea how to fix it i will be grateful.

P.S. of course this code run after authentication where i use user that
can change logon howers through "Active Directory Users and Computers"

ldap = Net::LDAP.new
ldap.host = "192.168.0.2"
ldap.port = 389
ldap.auth "CN=User for Maintenance,OU=Other Users,DC=example,DC=local",
"pass"

if ldap.bind
    ldap.open{|ldap|
      changelogonhours("Tom Bombadil",ldap)
    }
else
puts "nooooooo"
end
