Invalid character error occurs during search operation

Follow these steps to troubleshoot if an error occurs, which reports that an invalid character is found during a search operation.

Problem

An exception similar to the following example occurs while searching:

00000061 SystemErr
    R   Caused by: java.lang.RuntimeException:
An invalid XML character (Unicode: 0x0) was found in the element content: f _!l8

While this error might occur because the invalid character reported in the error messages does exist in the search result, it could also occur due to incorrect configuration of the external ID syntax.

Solution

First, check whether the invalid character that is reported in the error message does exist in the search result, as shown in this example:

00000061 LdapConnectio
< com.ibm.ws.wim.adapter.ldap.LdapConnection
searchEntities RETURN [DN: CN=test,DC=wimtest,DC=com  ExtId: f _!l8
UniqueName: CN=test,DC=wimtest,DC=com
Type: PersonAccountAttributes: {objectguid=objectGUID: f _!l8,
objectclass=objectClass: top, person, organizationalPerson, user,
samaccountname=sAMAccountName: test, sn=sn: test, cn=cn: test}]

Remove the invalid character.

If the problem persists, the error might be caused by an incorrect configuration of the external ID in the wimconfig.xml file. For example, in the following configuration, the default syntax type is String.

<config:externalIdAttributes name="objectguid" /> 

The valid syntax configuration for external ID in this example is shown here:

<config:externalIdAttributes name="objectguid“ syntax=“octetString” /> 

The following table lists the default external ID attributes and syntax used by virtual member manager.

LDAP type	External ID attribute	Syntax
IBM Directory Server (IDS)	ibm-entryUUID	String
Microsoft Active Directory (AD)	objectGUID	octetString
Sun ONE Directory Server	nsuniqueId	String
Novell Directory Services	GUID	octetString
Other	DistinguishedName	String
