Outlook Mobile ask each logon for password


  • since a couple months the outlook mobile client, on Andraoid, and iPhone ask us each logon for the user credentials. In the past this works without any issue, but on this moment, I can’t find the solution for it.
    We run Kopano on our UNC Server, so logon’s are don with Ldap.
    Hopefully one of you can put me in the right direction, to resolve this issue.
    Thanks!


  • Which kopano-core version are you using? What you describe sounds a lot like the LDAP issue we’re discussing in this thread: https://forum.kopano.io/topic/3316/can-t-contact-ldap-server/20

    I experienced the ‘clients ask for user credentials’ as well, and it was resolved by upgrading to core-10.0.6.496 . I still see LDAP errors in the server.log, but the clients now work without constantly asking for (already locally stored) credentials.

    As @alexthetiger68 pointed out the current version of Kopano, Z-Push and potentially your os could help.

    Mobile phones use Z-Push to synchronise, normally after the password was changed phones (re-)ask the password. Some logging would be helpful, you can check https://wiki.z-hub.io/display/ZP/Debugging for debugging instructions for Z-Push.


  • Thanks for your replay, I’ve the following versions installed on my server.
    Kopano core 8.7.1.0-1 installed
    Z-push 2.4.5 installed
    Theses are the latest one that are available on UNC.
    on the push log I see the following.

    And on the error log I see the following

    10/10/2020 07:07:00 [22871] [FATAL] [wim] Exception: (AuthenticationRequiredException) - Access denied. Please send authorisation information

    Hi @goudduif,

    Z-Push 2.4.5 is not the latest version. The current stable is 2.5.2 and 2.6.0 final will be released soon.

    And on the error log I see the following

    10/10/2020 07:07:00 [22871] [FATAL] [wim] Exception: (AuthenticationRequiredException) - Access denied. Please send authorisation information
    
    

    It looks like the app doesn’t send the credentials to Z-Push. I suppose it has token based authentication now, so it would be helpful if you would provide the full request headers.

    However I fully agree with the advice you got at the univention forum - do not use Outlook mobile client.

    On Univention I still didn’t see a newer version off the Z-push application

    There’s Kopano blog post regarding UCS updates: https://kopano.com/blog/staying-up-to-date-with-kopano-releases-on-ucs/

    What about my other notes, especially regarding request headers?
