If the user connected
via LDAP with the UID connection option, there is no reason to use
this option. Use TD_LOG_MECH_TYPE= and TD_LOG_MECH_DATA= to allow
LDAP authentication for TPT if the user did not specify LDAP authentication
for UID in the connect string. You can also use this option with TD_LOG_MECH_DATA=
to override the LDAP ID specified in the UID option with a different
LDAP ID.
