PI82111:Federated repositories fails to change password when JRE is Java 8

Download Description

PI82111 resolves the following problem:

ERROR DESCRIPTION:
When running on Java 8, Federated Repositories will fail to update user password in Active Directory

PROBLEM SUMMARY

USERS AFFECTED:
IBM WebSphere Application Server users of federated repositories

PROBLEM DESCRIPTION:
When running on Java 8, Federated Repositories will fail to update user password in Active Directory.

RECOMMENDATION:
Install a fix pack or interim fix that includes this APAR.

In the Java 8 release, the JRE was updated to use NIO converters instead of IO converters, which were removed. The IO converters handled the endian-ness based on the platform. When moving to NIO, the Java specification was corrected to give consistent behavior (big endian) for all platforms when using the "UNICODE" charset.

The specification for encoding for the "unicodepwd" attribute requires it to be little-endian. Therefore, it can be expected, that on all little-endian platforms attempting to change a password will result in a OperationNotSupported / WILL_NOT_PEFORM exception being returned from Active Directory Server.

PROBLEM CONCLUSION:
Updated the encoding for the "unicodepwd" attribute value to always use the "UTF-16LE" charset to ensure it is always little-endian.

The fix for this APAR is currently targeted for inclusion in fix packs 8.0.0.14, 8.5.5.13 and 9.0.0.5. Please refer to the Recommended Updates page for delivery information:
