When trying to look up users from an AD LDS user store the following error appears in the server logs:
08:20:35,543 ERROR [ims.llsdk.directory.jndi.searcher] (http-/0.0.0.0:8080-1) javax.naming.OperationNotSupportedException: [LDAP: error code 12 - 00000057: LdapErr: DSID-0C090753, comment: Error processing control, data 0, v1db1 ];
Export your directory.xml file and modify the following line:
<DirectorySearch maxrows="[A NON ZERO NUMBER]" maxpagesize="[A NON ZERO NUMBER]"/>
Change that line to <DirectorySearch maxrows="0" maxpagesize="0"/>
Once that has been changed, import the modified xml file back into your environment.
