LDAP & Exchange online server RRS feed

  • Question

  • hello all,

    in my CPE environment, i'm using a LDAP client that connects to Exchange Global Address Book in order to make contacts searches.

    now i also have an office365 account with Exchange server hosted this time by MSFT.

    but i'm not sure at all that my LDAP client will continue to run ???

    do someone know if Office365/Exchange online is offering the LDAP service ? that will allow me to look for only the contacts of my organization etc.... ?

    of course, in Outlook it works => when my Exchange account is configured, in the TO field of an email I can add a recipient after a search on the Global Address List that presents only the contacts of my organization. But this is probably not based on LDAP.

    not sure, LDAP on GAL is supported with O365.

    thank you

  • There is no LDAP endpoint for Office365 but if you still have a local Ad (eg Hybrid or DirSynced) then you should still be able to point to the local AD dc's LDAP endpoint. Otherwise in addition to what Mark has mentioned you have the Azure Graph REST api or EWS FindPeople (but all of these rely on this being a development question where you can change the code to use these API's, if your limited to what a Cicso CPE device can do then can then I would suggest you contact Cisco directly).

  • Hello Jerome

    Thanks for the question.

    You can setup  a one way sync from On premises LDAP servers to Exchange online using Directory Sync servers. This is what we do in hybrid exchange environment with Exchange Online.

    You can check details and able to make some changes in accounts using the Azure AD Powershell.

    Deploying directory sync servers:-

  • thanks a lot for your answer but my goal is to reuse my LDAP client.

    i know possibilities exists to get contacts but i need LDAP ;-)

  • thanks but you're right i don't want new developments.

    anyway the situation with hybrid deployment is interesting. thanks

  • thanks this notion of hybrid deployment is the only one that can work for me.

    if i want directory features it seems i need to develop using MSFT APIs (Azure REST, EWS etc...)

    thanks all for your answers
