PHP Fatal error: Call to a member function composeAndStoreDisplayName() on null in /var/www/owncloud/apps/user_ldap/lib/access.php on line 584

looks like it's LDAP-related. @owncloud/ldap

[DeepDiver1975]

We did fix this in 9.1 and master: #25598 and #25601

Looks like we need to backport this to stable9

@jvillafanez please have a look - THX

[jvillafanez]

@DeepDiver1975 That patch is also in 9.0.5. The code explodes in the access.php file.

oh ... you are right! hehe - sorry for the noise

[jvillafanez]

@odesport any additional information you could provide to reproduce the issue? Any user in LDAP with weird name? Did you delete an user from LDAP before updating the ownCloud instance or something similar?

@odesport if you can rollback your installation to the state prior upgrading ownCloud and try the patch, it's very appreciated.

@owncloud/qa Please verify the #26337 patch doesn't break any working installation and fix this issue 👼

Thanks for the patch.

Some LDAP users have probably been deleted.

I've modified the file apps/user_ldap/lib/access.php in my 9.05 stable version, like in the patch and restored my 8.2 version before upgrading. The error doesn't appear any more but the script has been launched for 20 hours and only 22000 LDAP accounts have been parsed (There are 400 000 entries in my oc_ldap_user_mapping production table). Why is it so long ?

[jvillafanez]

@DeepDiver1975 Any action during the upgrade 8.2 -> 9.0 that needs to retrieve the whole list of users? I'm thinking in the "generate birthdays" thing, but I'm not sure when it was introduced.
