Clear the cache directory (/usr/share/webconsole/work/Standalone/localhost/apoc/jsp/) where tomcat stores its compiled JSPs.
Verify that the file policymgr.cfg exists (/usr/share/webconsole/apoc/WEB-INF/).
Verify that the file policymgr.cfg has correct user rights (read access for noaccess:noaccess).
Verify that the LDAP data stored in the file policymgr.cfg corresponds to your LDAP server, such as host, port, baseDN, and so on.
