LDAP_BIND_TIMEOUT={
bind_timeout_seconds|
120}

The default timeout period is 120 seconds. If this period expires, the bind times out. A signon failure occurs because the PowerExchange user cannot be authenticated.
LDAP binds occur twice during PowerExchange user authentication: once to authenticate the search user and a second time to authenticate the PowerExchange user. Each bind uses the LDAP_BIND_TIMEOUT value.
