Tivoli Access Manager Trust Association Interceptors require the creation of a trusted user account in the shared LDAP user registry. This is the ID and password that WebSEAL uses to identify itself to WebSphere Application Server. To prevent potential vulnerabilities, do not use sec_master as the trusted user account and ensure the password you use is unique and generated randomly. The trusted user account should be used for the TAI or TAI++ only.
Use either the Tivoli Access Manager pdadmin command line utility or Web Portal Manager to create the trusted user. For example, from the pdadmin command line:
Example
pdadmin> user create webseal_userid webseal_userid_DN firstname surname password pdadmin> user modify webseal_userid account-valid yes
