Usernames are shown in Circle Member List instead of given name

[Volker-K]

Steps to reproduce

1. Use both LDAP and internal accounts
2. Create a circle from an LDAP account
3. Add members that are identified by LDAP and other identified internally
4. Only LDAP users are shown with their given name in some circle's members list, users that are authenticated internally are shown with their userid only what makes it difficult to tell who is who in larger circles

Expected behavior

All users should be listed with their given name

Actual behavior

Only users authenticated via LDAP are shown with their given name in serveral circles.

Example:

All userids beginning with "ocdu" are authenticated internally and userid and given name are set correctly, the others with their given name shown in this list are authenticated via LDAP.

First Idea: Circles ist using cached names in its database tables. I already hat a support case with an obsolete given name (after a marriage) that was sown correctly in the whole Nextcloud installation except for Circles.

Could it be that a malfunction of an older Circles or Contacts version caused the wrong names to be cached in this case?

Maybe there's an undocumented command to refresh this cache?
