Policy Server:

[4332/139870634764032][Tue Jul 14 2020 03:27:17][SmDsLdapConnMgr.cpp:1201][ERROR][sm-Ldap-02230] Error# '4' during search: 'error: Sizelimit exceeded' Search Query = '(objectclass=group)' for server '<LDAPSERVER>:<PORT>'

 

Environment

 

Release : 12.8.03 (SP3), 12.8.04 (SP4), 12.8.05(sp5)

 

Resolution

 

The "error: Sizelimit exceeded" message means that the Active Directory AD server is configured to return a certain number of results (with the MaxPageSize parameter), and the query should return more than this value (1).

There is some explanation on how to increase MaxPageSize on the Active Directory (2).

Discuss the suitability of doing this with the Active Directory AD admin first.
