(directory path) where the table is located. The owner of the password table, typically the
SPD Server administrator, can update the table.
The password table contains the following attributes and capabilities for each system user:
• a user ID
• a password
• an access privilege
• an optional IP address
• an optional password expiration time
• an optional ACL group name
• an optional time limit between successful logins
• an optional number of login failures before disabling the user
• an optional user performance class (currently not implemented)
A user ID is are restricted to 8 characters and does not have to correspond to any system
user ID.
A passwords is also restricted to 8 characters.
A password for the psmgr table must have a minimum of 6 characters - at least one character
must be numeric, and at least one character must be alphabetic. A new password must be
different from a user's last six passwords. The password cannot contain the user ID.
If a user has three consecutive failed attempts to connect to the SPD Server host, his or her
user ID is no longer enabled. Until an administrator resets the user ID, the user will not be
able to connect to the SPD Server host.
If you are upgrading to SPD Server 4.5 from SPD Server 3.x, the SPD Server 4.5 psmgr
utility must be re-populated from the SPD Server 3.x password table.
Invoking the psmgr Utility
You invoke the psmgr utility by entering the PSMGR command and specifying the
directory path where the password table is located. (Or you can specify a password table
that has not yet been created.)
For a UNIX system, use the command:
psmgr installdir/site
The command invokes the psmgr utility and specifies the directory path for the password
table.
For a Windows system, use the command:
psmgr
The command invokes the psmgr utility and uses the directory where SPD Server was
installed to access the password table.
Converting to a psmgr 4.x Table
With SPD Server 4.5, you must convert your SPD Server 3.x password file to 4.5 format.
Converting your password file to 4.5. format enables you to use the same set of active SPD
Server user IDs in SPD Server 4.5 that you used in SPD Server 3.x. To convert your SPD
Server password file to 4.5 format from 3.x format, do the following:
