When using latin charset database some functions in /auth/ldap/lib.php are missing proper
encoding checks and conversions if necessary. This will cause data loss when syncronizing database
with LDAP and it disables user accounts when username contains charachters like å, á, é etc...
Functions missing checks:

• auth_sync_users
• auth_get_userinfo_asobj
• auth_ldap_update_user_record
