Consider the following scenario:
Your IP address is <xxx.xx.xx.xx>, you have configured eDirectory on it, and your tree name is <XXX_TREE>.
You have a login cache that maps <XXX_TREE> to <xxx.xx.xx.xx>.
Because of network movement, you have got a new IP address <yyy.yy.yy.yy>, configured eDirectory on it, and the tree name remains same (<XXX_TREE>).
Another user has taken your previous IP address <xxx.xx.xx.xx>, and configured a new eDirectory tree <YYY_TREE>.
Now, if you log in to iManager with <XXX_TREE> tree name, you would log in to <YYY_TREE> because <XXX_TREE> maps to <xxx.xx.xx.xx>, but <xxx.xx.xx.xx> is currently configured with <YYY_TREE>.
Work around:
For Windows,
Go to ...\Program Files\Novell\Tomcat\webapps\nps\WEB-INF\.
Open config.xml file.
In the file, search for the Cached-Tree setting and delete your Tree Name value from the setting.
Delete the setting that starts with your tree name.
For Linux,
Go to /var/opt/novell/iManager/nps/WEB-INF.
Open config.xml file.
In the file, search for the Cached-Tree setting and delete your Tree Name value from the setting.
Delete the setting that starts with your tree name.
