Nextcloud login fails without displayName LDAP attribute

[stephdl]

User login fails in Nextcloud if the LDAP user node has no displayName attribute.

Steps to reproduce

• Install an openldap or samba AD account provider
• install nextcloud and configure it to use the ldap
• create a user in the LDAP without the displayName : foo.john
• try to login to Nextcloud

Expected behavior

I expect that my user can login

Actual behavior

My user cannot login, in fact it is refused until I go to edit the user an I add a display name foo john, then I can login to the Nextcloud

Components

core 2.8.0 openldap 2.2.3 nextcloud 1.1.6

QA

test case 1

• on NS8 install the core ghcr.io/nethserver/core:2.8.1-dev.1
• install an account provider
• create a user without display name
• you must be stopped, the display name is a mandatory

test case2

• on NS7 install an account provider openldap
• create some users
• install nethserver-ns8-migration
• yum install http://packages.nethserver.org/nethserver/7.9.2009/testing/x86_64/Packages/nethserver-ns8-migration-1.0.11-1.3.g2c9f4e5.ns7.x86_64.rpm
• migrate them to a NS8 server
• once migrated go to the NS8 and check if the display name of the users is migrated as well (it must be not not blank)
• login into the openldap container, do a slapcat or a ldapsearch gecos displayName and verify that you have the same field gecos and the same field displayName
