Hi, Using the LDAP service of a Lotus Notes / Domino server, I cannot get the telephone attribute for people. Sad it is but Lotus like M$ call it telephonenumber. I use ‘net/ldap’ for this which works fine for other attributes. Net::LDAP#search delivers an Array of Net::LDAP::Entry objects, and I can call attributes like the following simplified example shows: ldap.search( :base =\> base, :filter =\> ldap\_filter ) do |entry| puts “DN: #{entry.dn} Name: #{entry.givenname} #{entry.sn}” end Now, it looks like the telephonenumber attribute is not delivered. Having done a simillar application in Perl (using Net::LDAP) which still works with the same LDAP server and parameters, I know the attribute should be there. But the following results in a NoMethodError exception. ldap.search( :base =\> base, :filter =\> ldap\_filter ) do |entry| puts “Phone: #{entry.telephonenumber}” end Using entry.telephone doesn’t help, and adding the attribute list to the Net::LDAP#search (e.g. [:dn, :sn, :telephonenumber]) doesn’t help. Btw: In the above code block I tried entry.methods.sort and was really surprised it did not show things like ‘dn’ or ‘mail’ as its methods; however they are working. Any idea how to get this telephonenumber attribute? MP ---

Hi. Strange: Looks like somebody posted a reply which I could not see - neither in the news reader nor in [groups.google.com](http://groups.google.com). The sender’s ID was ‘garbagecat10’. I found the reply when giving it another trial under “Forbiddenweb Archive”. Anybody any idea what happened there? Ok, here is the contributor’s question back to me, so he/her or anybody else may have further ideas: > What happens if you use Net::LDAP::Entry#each to dump > out all of the attributes that were returned from the > server? This results in the following list: roaminguser mailsystem sn checkpassword cn messagestorage passwordchangeinterval displayname encryptincomingmail uid passwordgraceperiod originalmodtime roamcleansetting givenname objectclass roamcleanper mail maildomain personaltitle availablefordirsync dn So no telephonenumber, no telephone. Any further ideas? Thanks to all of you. MP ---

Ok, that’s really weird. Did you try setting the attributes parameter to Net::LDAP#search? If that doesn’t work, then please try something like ldapsearch and verify that the attribute really is returned. (I know you said Net::LDAP in perl worked, but I’d like a little more confirmation.) If that fails, then it could be a bug in Net::LDAP and I’ll want to follow up with you offlist to track it down. ---

If you have access to the LDAP server admin, you might want to ask if there is a filter preventing anonymous binds from revealing the telephone attribute. Your code seems to imply that your are doing anonymous binds. ---

Anyway to turn logging way up on the server side so you can compare the requests that work against those that don’t? Mike B.
