Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server                                      *
****************************************************************
* PROBLEM DESCRIPTION: When LDAP user registry returns a DN    *
*                      name which contians non ASCII           *
*                      characters, LTPAToken creation might    *
*                      fail.                                   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Due to a code defect, there is a possiblity that LTPAToken
signature cache code doesn't generate cache key which
maintains uniqueness based on given Access ID. When this
condition happens, a validation of newly created LTPAToken
might fail because an incorrect signature which was returned
from LTPAToken signature cache is attached to the token.
This condition might happen when Access ID string contains non
US-ASCII characters.

Problem conclusion

With this fix, LTPAToken signature cache code maintains
uniqueness of cache key to avoid this issue.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.31, 8.0.0.8, and 8.5.5.2.  Please refer to the
