The IQ login management stored procedures (sp_iqaddlogin, etc.) have been enhanced to manage user logins in the multiplex environment. On any server in the multiplex environment, user passwords can be set to expire at a certain time, a user can be locked out of a database, and a user can change his password and reset the expiration time. This feature requires that all servers in the multiplex are running IQ 12.6 and the database is upgraded. For more information, see Sybase IQ System Administration Guide.
