Setting Resource Limits Based on Bind DN
You can control or set limits on search operations for directory data using special
operational attribute values on the client application binding to the directory.
Table 18-1 lists attributes that you can use to set search-operation limits.
Note that Directory Manager receives unlimited resources by default. The resource
limits you set for individual binders takes precedence over the default resource
limits you set in the global server configuration. Also note that the appropriate
settings for these limits are deployment specific. You should conduct extensive
analysis of server behavior with different settings under loads similar to your
expected usage pattern before deployment.
Troubleshooting
• The plug-in makes HTTP requests for each queried IM Status attribute. Make
sure that the machine in which the presence-enabled Directory Server is
installed has HTTP access to the Internet.
• In case of erroneous presence results, to better understand the point of failures,
enable error logging for plug-ins.
