/mcpDescription Service Parameter Specifies the maximum number of LDAP directories (also known as agreements) that can be configured in the LDAP Directory window in Cisco Unified CM Administration (System > LDAP > LDAP Directory). Creating more than one LDAP directory helps in synchronizing users from more than one search base. Note You must restart the Cisco DirSync service for changes to this parameter to take effect. Default setting: 5 Minimum: 1 Maximum: 5 Maximum Number of Agreements Specifies the maximum number of LDAP host names that can be configured for failover purposes. Note You must restart the Cisco DirSync service for changes to this parameter to take effect. Default setting: 3 Minimum: 1 Maximum: 3 Maximum Number of Hosts Specifies the number of seconds to delay before retrying the Unity Connection to the first LDAP server (hostname) that is configured in Cisco Unified CM Administration. After a Unity Connection failure, the system tries three times with reconnect to the same host. When the third attempt is also unsuccessful, the system attempts to connect to the next host name in the list in hierarchical order. Default setting: 5 Minimum: 5 Maximum: 60 Retry Delay on Host Failure (secs) Specifies the number of minutes to delay before retrying every LDAP server (hostnames) that is configured in Cisco Unified CM Administration. Unity Connection to LDAP servers are retried in the order they appear in Cisco Unified CM Administration and three attempts are made based on the delay interval specified in the Retry Delay On Host Failure service parameter. When all three attempts fail, the next LDAP server in the list is tried. If the system is unable to connect to any of the servers in the list, an error gets logged and the system waits until the next sync interval before retrying to connect starting with the first server in the list. Default setting: 10 Minimum: 10 Maximum: 120 Retry Delay on HostList Failure (mins) Specifies the number of seconds allowed for establishing the LDAP connection in Unity Connection. The LDAP service provider aborts the attempt if a connection to Unity Connection cannot be established in the specified amount of time.
