ldap_write_support not working with nextcloud 29.0.0.19

[mrdrmmn]

I'm new to nextcloud and have a fresh install of 29.0.0.19 with and ldap backend for users. authentication is working as expected and verified to be coming from LDAP. When I enable ldap_write_support, I immediately start seeing the following errors in my logs:

But I do in fact have an LDAP provider configured and working.

I've been digging into the code and have not been able to determine what the exact problem is. I suspect maybe things have changed in nextcloud that have caused this to become an issue as I am sure others have been working just fine.

I'll continue to poke and it and if I can find a solution, I will update this.

[mrdrmmn]

This demonstrates a valid config:

# sudo -u www-data php occ ldap:test-config s01
The configuration is valid and the connection could be established!
# sudo -u www-data php occ ldap:check-user test
The user is still available on LDAP.

But any attempts to modify the password of an ldap user (sudo -u www-data php occ user:resetpassword test) generates the same error as provided in the initial report.

Let me know if there is anything I can do to provide better/more helpful detail.

I can confirm this with 29.0.3. The log is flooded with these errors, although there are no functional restrictions. It affects those users that are created as SQL/local.

What is the value of ldapProviderFactory in your config?

[come-nc]

I cannot reproduce on latest main branch with server master. Did not test on 29.

@mrdrmmn @Beerlesklopfer We need details on the situation to find the source of the problem because we are not able to reproduce it.
Without answers I will close this ticket.
