Securely Storing the LDAP Credentials
You can enable the IP phone to securely store the LDAP user credentials when Broadsoft Flexible Seating feature
is enabled. When the user logs into the guest profile next time, he/she can access the LDAP directory directly
instead of entering the LDAP user credentials again.
The IP phone can store up to 100 LDAP user credentials. If the number of user credentials reaches 100, the user
who has the longest inactivity period is removed from the phone when any additional user is added.
The LDAP user credentials persist after the phone reboots.
