Abstract:  Authentication fails if a user's userid contains a single quote.

Description/symptom of problem:  
PK41516 resolves the following problem:

ERROR DESCRIPTION:                                              
With WebSphere 6.1.0.3 configured for Federated Repositories    
using the file repository and the user exists there,            
if a user like Joe O'brien or email joe_o'brien@company.com     
tries to log in to WebSphere it will fail to authenticate.      

LOCAL FIX:                                                      
do not use users in the file repository with single quotes      

PROBLEM SUMMARY

USERS AFFECTED:
IBM Websphere Application Server version
6.1 users who use federated repositories
(virtual member manager).

PROBLEM DESCRIPTION:
Authentication fails if a user's
userid contains a single quote.

RECOMMENDATION:
None

When a user's userid contains a single quote ('),
authentication fails because the XPath expression uses single
quotes as a delimiter.

PROBLEM CONCLUSION:                                             
If the userid contains a single quote, virtual member manager   
will use escaped double quotes in the XPath expression.         
                                                                
For example the following query uses escaped quotes             
around bi'll, instead of using single quotes:                   
                                                                
expression="@xsi:type='PersonAccount' and                       
            principalName=\"bi'll\""                            
                                                                
                                                                
This fix is targeted for fixpack 6.1.0.9.
