Username or password incorrect

sirio81

Hi all, I installed z-push 2.3.8 on debian 9 (z-push-config-apache) and the zimbra backend (67).
When I try to add a new account on my smartphone (Android 6.0), it fails.
In z-push.log I see

Exception: (AuthenticationRequiredException) - Access denied. Username or password incorrect

Off course I’m sure I’m using the right user name and password: double checked logging into zimbra.

I found other users that complained about it and that solved it by setting the option

define('USE_FULLEMAIL_FOR_LOGIN', false);

to ‘true’, like shown here.

It’s already set to ‘true’ in my z-push.conf :-/
On my smartphone I tried to use ‘username’ or ‘username@domain.com’ but it doesn’t work either ways.
Any suggestion?

PS: my zimbra isn’t very recent:
Release 7.2.2_GA_2852.RHEL5_64_20121204211814 CentOS5_64 FOSS edition
