[pve-devel] [PATCH v2 access-control] fix #5136: ldap: Decode non-ASCII characters in attributes

[Filip Schauer <f.schauer@proxmox.com>]

UTF8 decode non-ASCII characters when syncing user attributes, since
those will be encoded later on. Without this fix the attributes were
encoded twice, resulting in cases such as 'ü' turning into 'ü'.

Changes since v1:
* Do not try to URI unescape the user attributes, since we do that later
  in PVE::AccessControl::parse_user_config anyways.
