When CUCM is using LDAP for authentication several subsystems including CTI manager utilize this mechanism for device authentication. One for example is the CTI manager the invokes an LDAP authentication process with LDAP when a CUPC user enabled deskphone control.
Generally most LDAP querys (aka searchRequests) have a sizeLimit and timeLimit variable that can control to overall response in addition to the filter.
When an Tomcat authentication request takes place these size and time Limit Values are sent to the LDAP server with 0's for each.
When a CTI authentication request takes place the SizeLimit value is 0, however the timeLimit value is 1996501041 . This variable seems to cause issues with Sun One LDAP systems where the LDAP server returns a timeLimitExceeded... I can execute the exact same searchRequest with a stand alone browser with a timeLimit of 0 and get the appropriate response every time.
Does anyone know why this timeLimit value gets populated on CTI requests from CUCM or what this value actually represents?
