Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server                                      *
****************************************************************
* PROBLEM DESCRIPTION: Login might fail if user distinguish    *
*                      name contains # (number sign).          *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The LDAP specification indicates, if a # (number sign)is
located at the beginning of value of element (i.e., cn=#user),
it needs to be escaped by a backslash (i.e., "cn=\#user").
When a LDAP server returns a DN name with this string
sequence, the original code escaped a backslash character
again (i.e., "cn=\\#use"r). As a result, when this string is
used for bind request, LDAP server returns an error because it
could not find the corresponding object.

Problem conclusion

With this fix, number sign is handled properly.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.23 and 8.0.0.4.  Please refer to the Recommended
