    Exclamation German Characher with LDAP search

    Hi ;

    I have problem with LDAP, when I search on DN that have any germane character like ö,ü ,ä that return exception , although that DN is exists.

    I search on DN like 'CN=***ü***,CN=*******,DC=*******t,DC=de'

    The Exception is:
    Code:
    org.springframework.ldap.NameNotFoundException: [LDAP: error code 32 - 0000208D: NameErr: DSID-031001C6, problem 2001 (NO_OBJECT), data 0, best match of:
	'CN=*******,DC=*******t,DC=de'
nested exception is javax.naming.NameNotFoundException: [LDAP: error code 32 - 0000208D: NameErr: DSID-031001C6, problem 2001 (NO_OBJECT), data 0, best match of:
	'CN=*******,DC=*******,DC=de' remaining name ''
Caused by:

    Class Attributes Mapper:
    Code:
    class ObjectGuidMapper implements AttributesMapper{

	public Object mapFromAttributes(Attributes attributes)

		if (attributes.get("distinguishedName") !=null){ //distinguishedName
				objectGUID.setDn(attributes.get("distinguishedName").get().toString());
		}

		if (null != attributes.get("objectGUID")){
			byte[] guid = (byte[])attributes.get("objectGUID").get();
				objectGUID.setGuid(decodeObjectGUID(guid));
		}
		return objectGUID;	
	}
}

    Your stack trace refers to the method findLdapAttributes, which is not included in your posted code. Are you certain your code works for "normal" entries (i.e. entries with ascii DNs)?

    yes, findLdapAttributes method is same as findObjectGUID , but with different criteria search. and the two method throws same exception.

    findLdapAttributes method return List of DN attributes name, and findObjectGUID return List of DN with ObjectGuid.

    findLdapAttributes method:
    Code:
    	public List findLdapAttributes(){

		logger.info("Reading LDAP attributes...");

		List attList = new ArrayList();

		try{
			attList = (List)ldapTemplate.lookup("", new AttMapper());
		}
		catch(Exception exp){
			logger.error("findLdapAttributes", exp);
			throw new LdapFetchingDataException(exp);
		}
		return attList;
	}
    AttMapper:
    Code:
    	class AttMapper implements AttributesMapper{
		public Object mapFromAttributes(Attributes attributes)
		throws javax.naming.NamingException {

			NamingEnumeration ne = attributes.getIDs();
			
			List attList = new ArrayList();
			String attID = "";

			while(ne.hasMore()){
				attID = ne.next().toString();
				
				attList.add(attID);
			}

			return attList;
		}
	}
