Registry Settings Used for 3270 Single Sign-On

  • Cikk

The 3270 Single Sign-On feature depends on Microsoft® Host Integration Server scanning 3270 logical units (LUs) used in the logon process for special keywords that are defined in the registry on the computer running Host Integration Server. The values for these special keywords can be defined by the system administrator on the computer running Host Integration Server.

The registry settings used by the 3270 Single Sign-On process are located under the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services registry node. The following entries are installed under the SNASERVR\PARAMETERS subkey:

3270SSOPadByte
This entry should be set to an ASCIIZ string to use as the character for padding replacement text in the user name or password if these strings are shorter than the length of the special tag strings defined below. The default value for this pad character is the ASCII space character.

3270SSOPostReplaceCount
This entry should be set to a DWORD that represents the number of message chains of RUs to scan after replacement of text for user name or password. The default value for this number is 10.

3270SSOPrefix
This entry should be set to an ASCIIZ string to use as the special prefix tag string in combination with the user name and password tags. The default value of this string is MS$.

3270SSOPwdTag
This entry should be set to an ASCIIZ string to use as the special tag string in combination with the 3270SSOPrefix tag in defining the special host password string that will be replaced. The default value of this string is SAMEP, so the default host password string that is scanned for and replaced is MS$SAMEP. Note that length of the password string that is scanned for (MS$SAMEP, for example) determines the maximum length of the password string that can sent to the host using Single Sign-On. This limit occurs because the password substitution cannot change the length of the data message. Note that the value of this string must be different from the value of the 3270SSOUserTag entry for Single Sign-On to function properly.

3270SSOReplaceCount
A DWORD value that affects the time-out value for password substitution. User IDs and passwords will be substituted in each chain on the LU-SSCP and PLU-SLU sessions until the timer expires. By default the timer will be set to 30 seconds, but this behavior can reconfigured in the registry using the 3270SSOReplaceCount and 3270SSOReplaceTimer registry entries. The timer is started when the OPEN SSCP is received by the node.

If the 3270SSOReplaceCount registry entry is defined and the 3270SSOReplaceTimer registry entry is not defined, the node counts this number of RUs (on PLU-SLU session only) before time-out occurs. If both the 3270SSOReplaceCount and 3270SSOReplaceTimer registry entries are defined, the value for 3270SSOReplaceCount will be used to determine when a time-out will occur. By default, this key is not defined and the node defaults to a time-out of 30 seconds.

3270SSOReplaceTimer
A DWORD value that affects the time-out value for password substitution. User IDs and passwords will be substituted in each chain on the LU-SSCP and PLU-SLU sessions until the timer expires. By default the timer will be set to 30 seconds, but this behavior can reconfigured in the registry using the 3270SSOReplaceCount and 3270SSOReplaceTimer registry entries. The timer is started when the OPEN SSCP is received by the node.

If the 3270SSOReplaceTimer registry entry is defined and 3270SSOReplaceCount is not defined, the node uses this value in seconds before time-out occurs. If both the 3270SSOReplaceCount and 3270SSOReplaceTimer registry entries are defined, the value for 3270SSOReplaceCount will be used to determine when a time-out will occur. By default, this key is not defined and the node defaults to a time-out of 30 seconds.

3270SSOUserTag
This entry should be set to an ASCIIZ string to use as the special tag string in combination with the 3270SSOPrefix tag in defining the special user name string that will be replaced. The default value of this string is SAMEU, so the default user name string that is scanned for and replaced is MS$SAMEU. Note that length of the user name string that is scanned for (MS$SAMEU, for example) determines the maximum length of the username string that can sent to the host using Single Sign-On. This limit occurs because the user name substitution cannot change the length of the data message. Note that the value of this string must be different from the value of the 3270SSOPwdTag entry for Single Sign-On to function properly.
