DB2 9.1.2
Windows Server 2003

When I try to connect to a database, I receive this message:

db2 connect to xxxx user dbi
SQL30082N Security processing failed with reason "19" ("USERID DISABLED or RESTRICTED"). SQLSTATE=08001

I can make Windows logon with that user.

With another user I can connect to that database.

db2diag.log shows this messages:

Thank you,

This technote may help:
IBM - SQL30082N with rc=19 when trying to connect to a database on a new installation of DB2 Universal Database Version 8.2 on Windows.

Solved the problem deleting this user and creating a new one with the same name. That works.
