    LDAP and Outlook 2000 (2000 Office SP3)

    I've recently installed a Windows 2003 server on the network. We use MDaemon as our e-mail server software with clients connecting via POP3. This works fine, but one problem is the management and distribution of centralised e-mail lists. I've used Active Directory to set up users in a dedicated OU tree, and entered e-mail address and telephone details for each user and some mailing lists as contacts. Outlook is then able to connect to this directory via LDAP and retrieve the information. I've also created an ASP page on our intranet to use LDAP to populate an internal phone and e-mail list. All this works a treat, but I have two issues that I was hoping someone may be able to help me with.

    1. Is there a way to tell Outlook 2000 to do an LDAP lookup before it looks in the users Contacts folder for e-mail addresses? Previously I was using an "internal" contacts list synchronised to Mdaemon, and it was fairly easy to alter the order the contact folders were queried. With LDAP, the system seems to only want to look up in the order "local contact folders" and then LDAP.

    2. Does anyone know how to alter the authentication method used for the LDAP lookup. At the moment I can get Outlook 2000 to connect to LDAP if I change from Corporate service to Internet Only, or if I use Outlook Express. I can't get Outlook XP to connect to the LDAP server at all. The key setting that is available with Internet Only Outlook 2000 and Outlook Express is "Log on using secure password authentication". Without this ticked I get no connection. If I tick it and enter username/password it connects a treat. Other Outlook setups don't seem to offer this alternative, and won't connect.

    Hi,
    Re your question 2 and Outlook XP, have you tried Tools-Email accounts, then select the 'Add a new directory or address book' option, choose 'Internet Directory Service (LDAP)' and fill in the relevant information?

    Yes. You can set up an LDAP connection, but it won't connect. Outlook XP doesn't seem to have the "Use Secure Password Authentication" option that my Win 2003 server seems ot require. I hit the same problem with the Outlook 2000 Corporate setup (which gives you "services" in the tool menu rather than "accounts"). If you go into Sevices in Outlook 2000 and set up an LDAP connection, again there is no "Use Secure Password Authentication" option and I fail to connect. Switch to Internet only and set up the connection via "Accounts" in the tools menu, put a tick in "Use Secure Password Authentication" and it works a treat.

    Do you get an error message with your current setup? If so does <!mskb=329660>Microsoft Knowledge Base Article 329660<!/mskb> have any relevance? Or do you simply get nothing happening?

    I only have one user running Office XP and they are at SP2. I'll apply SP3 and see if that helps them.

    However, everyone else is on Office 2000.

    Re: LDAP and Outlook 2000 (2000 Office SP3)

    Sorry to question what you have said about Secure Password Authentication. This option does exist in Outlook 2003 (and, from memory, in Outlook XP) under Tools|Options|Mail Setup|E-Mail Accounts|View or Change|Change - possibly under More Settings. HTH

    Re: LDAP and Outlook 2000 (2000 Office SP3)

    In Outlook XP in Change (same path as yours) there is a tick box for "This server requires me to log on". If I got to the More Setting, there is a tick box to use SSL. The latter does not seem to do the same as Secure Password Authentication. If you look at Outlook Express (XP SP2 version for example) you'll see that this has both a "Secure Password Authentication" (General Tab) and "SSL" (Advanced tab) option. The two are not the same. Having played with using Outlook Express to connect to AD/LDAP I can assure you the two are different.

    However, this is going off subject a little. Can anyone help me with changing the search order, so that systems check LDAP before contacts? Any suggestions on how I go about altering the LDAP access rights?

    Agreed: "Secure Password Authentication" and "SSL" are not the same option. At least, however, we seem to have resolved the second of your two questions.

    Re: LDAP and Outlook 2000 (2000 Office SP3)

    Ummmm. Well..... I'm still at the same point. I know how to set up Outlook 2000 (company standard) and Outlook Express to connect to AD via LDAP. However, as other Outlook set ups (XP and 2000 in Corporate mode) don't offer the "Secure Password Authentication" option, I'd like to know how I can change the authentication method at the server so as not to require this option at the client end - perhaps I should have put that more clearly.

    Also my main head ache is the search order.

    I appreciare the help so far.

    Re: LDAP and Outlook 2000 (2000 Office SP3)

    Edited by unkamunka to make the MSKB link "live"

    I think it may make sense to split this query in two. I've found this article:

    <!mskb=326690>Microsoft Knowledge Base Article 326690<!/mskb>

    But don't seem to have the tools it is suggesting I alter my settings with. I'll start a new post in one of the server forums to answer this part of the query.

    Therefore - Anyone any ideas for the search order in Outlook?

    On looking at the MSKB article, it seems that you will need to access dsHeuristic attribute using ADSI Edit. (ADSI Edit is a powerful low level editor, supplied by Microsoft in a free Resource Kit, that should be used with caution. HTH

    Re: LDAP and Outlook 2000 (2000 Office SP3)

    Thank you. I'll have a look at that resource kit.

    I've just found this: http://support.microsoft.com/?kbid=245830

    However, changing the user name to the cn=username,cn=domain format worked, but only if the "Log on using secure authentication" was ticked. So no improvement, just a slightly more complicated username string.

    Re: LDAP and Outlook 2000 (2000 Office SP3)

    Just a general point on entering web links in the Lounge - when you are making a post.

    If you want to enter a link to the Microsoft Knowledge Base (article 245830), you need to enter <!t>[mskb=245830]<!/t> - which produces <!mskb=245830>Microsoft Knowledge Base Article 245830<!/mskb>.

    Alternatively, you can make a ("any old") web address "live" by entering <!t>http://support.microsoft.com/?kbid=245830<!/t> - which produces http://support.microsoft.com/?kbid=245830.

    More detail is at <!help=19>Help 19<!/help>.

    Re: LDAP and Outlook 2000 (2000 Office SP3)

    Thanks for the advice. I used it in <post#=434120>post 434120</post#> which also explains why I'm no longer looking at changing the permissions at the server.

    Still looking for help with the search order - default is Contact then LDAP. I want to change it to LDAP then Contacts.

    If you choose Tools-Address Book... and then select Tools-Options, there should be an option to change which one appears first.
