    Question External LDAP GAL help (please)

    We are considering installing an LDAP server on another machine to be used to augment our GAL. We have a list of contacts that we need to treat as external recipients (they cannot have accounts). We have these people in a data file and there is NO WAY to access the AD/LDAP server they were exported from. So what I need to do (and I am a newb to LDAP ) is setup an ldap instance with the data we have in the csv file. We will then change the GAL configuration for teh domain from internal to Both and then add this LDAP server.

    My question is what is the structure (if that is the right word) in LDAP I need to coerce this data into so that it is picked up by the GAL?

    Or is it a matter of setting the proper filters etc in the configuration to pull what you want? If so I still need to know the internal attributes etc that need to be assigned data so that things are picked up.

    Is what we need to do possible or has been done before?

    Any and all help is most appreciated!

    regards,

    Well I was able to accomplish this with the help of jason in Support. The hardest thing was coming in cold to LDAP and having to get up to speed on it fast.

    Let me know what you need and I will be glad to help

    A copy of the schema you are using would be extremely helpful. I've had some success on my own at modifying the stock OpenLDAP schemas but I could certainly benefit from looking at one that is already working well.
    Thanks,

    I did not need to modify any schemas. I started to at first but that is because I did not know that OpenLDAP came with many schemas. I include these and they support all that I need.
    Code:
    include         /usr/local/openldap/etc/openldap/schema/core.schema
    include         /usr/local/openldap/etc/openldap/schema/cosine.schema
    include         /usr/local/openldap/etc/openldap/schema/inetorgperson.schema
    There is a WIKI page that shows the mapping of LDAP attributes to zimbra contact attributes.

    Here is a sample entry:

    Code:
    dn: cn=Jane Doe,ou=TenonUK,dc=capesafe,dc=com
    objectclass: person
    objectclass: organizationalPerson
    objectclass: inetorgPerson
    givenName: Jane
    cn: Jane Doe
    sn: Doe
    mail: jane.doe@mymail.com
    telephoneNumber: 410-555-1212
    fax: 410-555-1214
    mobile: 410 431 5341
    title: IT MANAGER
    physicalDeliveryOfficeName: Stockholm
    These attributes seem to work fine

    I want to do the same exact thing you did.

    Is there some kind of step by step tutorial available on how you do this (put contact list into ldap server and have Zimbra access it as external GAL)?

    An LDAP server is already installed on the Zimbra server. Can I use this, or do I need to install an external one on another server?

    Thanks for any help!

    No I did not write a tutorial. I spent so much time learning LDAP and troubleshooting sasl authentication that I barely had enough time to complete the task.

    I can help you as best I can in the forum.

    You need to know LDAP. If you do not know it you should learn it. If you need me too I will post a tutorial I used that helped me tremendously.

    Take a look at post#5 in this thread for tips on the ldap setup / attributes.

    You should NOT use the Zimbra LDAP server for various reasons. You need to set up your own individual one. It is not that hard Just make sure that if you do it on a machine with sasl libraries that you either know how to use sasl with ldap or you build openldap without sasl.

    It is working great for me.

    Really appreciate it.

    Could you please post the tutorial that you used? That would be a great start as I am beginning from ldap ground zero.

    Thanks!
