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

Component : SITEMINDER -WEB AGENT FOR APACHE

Resolution

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

See:

See the following non-Broadcom link for an explanation of how to increase MaxPageSize on the active directory:

You should discuss the suitablilty of doing this with your AD admin first.
