Hi, Firstly, I make Hue LDAP integration and then Cloudera manager user interface administration->security enter  LDAP information  and cloudera-scm-server restart via console    I am reaching the Cloudera manager interface but it does not accept any users (admin-admin) that I have used before and LDAP users.    I am getting a username password error for all users and passwords. I try to reset username &password via below link but it did not work.   http://mynotesonhadoop.blogspot.com/2017/07/reset-admin-password-on-cloudera-manager.html    I can see below logs in  /var/log/cloudera-scm-server/cloudera-scm-server.log   Caused by: org.springframework.ldap.BadLdapGrammarException: Failed to parse DN; nested exception is org.springframework.ldap.core.TokenMgrError: Lexical error at line 1, column 1.
