Steps to reproduce
- Setup OpenLDAP with Nextcloud
- Add jpegPhoto to LDAP users (~20-30 KB, ~600x600 for HiDPI screens) -> Refresh tool viewing LDAP to confirm full quality is in LDAP
- Login to Nextcloud with any of these users to force LDAP sync of avatar
Expected behaviour
- Visit Nextcloud user settings page to see profile photo —> See avatar that is a high quality resize of what was pulled from LDAP If Nextcloud has the ldap_write_support module enabled (with avatar updating setting enabled), and if Nextcloud has write access to OpenLDAP:
- Go back to your viewing tool for OpenLDAP and check jpegPhoto for users —> View that the jpegPhoto was not changed just because Nextcloud downloaded and resized it
Actual behaviour
- Visit Nextcloud user settings page to see profile photo —> View low quality and pixelated version of avatar If Nextcloud has the ldap_write_support module enabled (with avatar updating setting enabled), and if Nextcloud has write access to OpenLDAP:
- Go back to your viewing tool for OpenLDAP and check jpegPhoto for users —> View that the jpegPhoto was updated and made low quality
