Hello, I want to use external authentication with active directory. But when I try to authenticate I have following error:
2018-03-09 06:35:07,071 ERROR EncryptionAuthenticationProcessingFilter,http-nio-8080-exec-10:218 - An internal error occurred while trying to authenticate the user.
org.springframework.security.authentication.InternalAuthenticationServiceException: Uncategorized exception occured during LDAP processing; nested exception is javax.naming.NamingException: [LDAP: error code 1 - 000004DC: LdapErr: DSID-0C0907C2, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v2580^@]; remaining name '/'
Do you know what can be the problem?
