This seems to be a ongoing bug using LDAP authentication and having parentheses in the group name containing the user you are trying to bind to. I am using Community Edition 8.. The bug seems to have persisted through all version of 8. including the latest 8.2.5 that I’m currently running. Example:
This does NOT work:
CN=LDAPUser,OU=Service Accounts (Local),DC=Domain,DC=Local
We are using Server 2012 R2 for both the host server (IIS) and the domain controller. I tested multiple variations of the above and it consistantly fails with a parentheses in the OU name.
