iOS App keeps asking for Password

Hi all,

first environmental Information

NC Version 15.0.14
Operating system and version Ubuntu Server 16.04 LTS
Apache version 2.4.18
PHP version 7.0.33

Client is iOS on iPAD Version 13.7
with NC App 3.0.12

The user cannot log on to NC using the app. On the same device using Safari, everything is fine. I tried a full reinstall of the app, but without success. On the iPhone of the same user everything is fine, other users also do not experience issues.

User are authenticated using AD and LDAP.

In the logs i see:

Warning core Login failed: ‘username’ (Remote IP: ‘xxx’)
2020-11-12T12:34:41+0100
Warning user_ldap Bind failed: 49: Invalid credentials

Warning user_ldap Bind failed: 49: Invalid credentials
2020-11-12T12:34:15+0100
Warning user_ldap Bind failed: 49: Invalid credentials

I have checked LDAP setup, everything is OK, I can enumerate users, so the backed seems OK to me.

Looks like wrong password at first sight, but on the same device in the browser everything works with the same credentials.

I hope, anybody has an idea what might cause this issue.

Kind regards,

Jens Mickerts
