[12396/23006][Mon Sep 04 2017 11:24:50][SmDsLdapConnMgr.cpp:1231][ERROR][sm-Ldap-02230] Error# '85' during search: 'error: Timed out' Search Query = '(&(|(objectclass=organizationalPerson)(objectclass=inetOrgPerson)(objectclass=organization)(objectclass=organizationalUnit)(objectclass=groupOfNames)(objectclass=groupOfUniqueNames)(objectclass=group)(objectclass=organizationalperson)(objectclass=inetorgperson)(objectclass=IDMPerson)(objectclass=groupOfUniqueNames)(objectclass=IDMGroup)(objectclass=organizationalUnit)(objectclass=eTGlobalUser)(objectclass=eTGlobalGroup)(objectclass=organizationalperson)(objectclass=inetorgperson)(objectclass=IDMPerson)(objectclass=groupOfUniqueNames)(objectclass=organizationalUnit))(AssignedRoles=givenName))' 

It was observed that when user count is 90000, the error was not reported but when it reached to 95000, we are observing above error 
 

Cause:

Search Timeout needs to be increased in Policy Server configuration

Environment:

CA Siteminder Policy Server Product Name=CA Single Sign-On Policy Server Full Version=12.52 SP1 CR06 
CA SharePoint Agent Product Name=CA SiteMinder Agent for SharePoint Full Version=12.52 SP1 CR04.

Resolution:

Please add new registry variable SearchTimeout to increase search timeout in Policy server. 

Under this registry path 
HKEY_LOCAL_MACHINE\SOFTWARE\Netegrity\SiteMinder\CurrentVersion\LdapSessionServer\ 

Right click on LdapSessionServer -> New -> DWORD (32 bit) value this will create a variable and rename as below 
SearchTimeout 

Set the value of 40 (in seconds) 

This registry change should take effect automatically. However, if issue persists after making above registry chnages, please plan a policy server restart.
