I am using openldap client library 2.4.44 on Centos 7.3, LDAP v3 setting. I am having an issue with LDAP bind when the DN has encoded representation of special characters like é (e acute). Actual DN is CN=mithun,OU=Groupes de Sécurité,DC=mytest,DC=net and when it is sent by the app (frontend) to our backend, it is coming as CN=mithun,OU=Groupes de S\u00e9curit\u00e9,DC=insaaadev,DC=net. Basically, é comes encoded as \u00e9 which is as per the encoding mentioned here https://www.fileformat.info/info/unicode/char/e9/index.htm
To further try out, I directly hardcoded the DN to CN=mithun,OU=Groupes de S\u00e9curit\u00e9,DC=mytest,DC=net and that worked fine. I want to understand why it fails when the DN in the same format comes from the frontend app. Appreciate your help, thanks.
