 To check that the LDAP server is running, run the command `ps -ef | grep slapd`. If no process is listed, the LDAP server is not running. To remedy this, run the command `/var/Sun/mps/slapd-<instance>/start-slapd`, replacing <instance> with the instance name of your LDAP server (there will anyway be only one directory with that naming structure in `/var/Sun/mps`).

 Follow the instructions in the installation guide to run the deployment tool and prepare the LDAP server, please note that if the LDAP server uses non-standard attributes or object classes for its organisations, roles or users, or if users are not stored in `ou=People` containers, the file named OrganisationMapping needs to be modified to reflect these differences *prior* to running the `deployApoc` or `createServiceTree` scripts.

 ==== Finding a User in LDAP ====

 

 To check whether a given user identified by its <username> exists in the LDAP server, run the following command from any machine:

 

 `ldapsearch [-x] -h <host> -p <port> -b <base> <attribute>=<username> dn`

 

-where <host>, <port>, and <base> match the values found in either the [#ConfigureAPOCMgr APOC Manager configuration] or the [#ConfigureAPOCAgent APOC Agent configuration], and <attribute> is the unique identifier attribute specified during the [#ConfigureLockhart Web Console configuration] or found in the [#PrepareLDAP organisational mapping file].

If it returns multiple entries, this means the attribute used doesn't uniquely identify a user in the LDAP server and this must be changed, either by using a different attribute or by modifying one of the duplicate entries.

 ==== Testing a User Password in LDAP ====

 

-To check that a user/password combination is valid for use with the APOC Manager, first run the command used to [#FindUser find that user]. The result of that command will contain a line formatted like `dn: uid=username,<blablabla>,<base>`. The string after `dn:` is the full DN of the user. Then perform the same search, but this time authenticated as that user, by adding before the `-h` flag in the command the string `-D "<full DN>" -w <password>`. If the command returns `Invalid credentials`, the user/password combination is invalid. The best course of action is then to reset the password to a known value using an LDAP administrative tool.

 ==== Configuring the Web Console ====

 

 To check the web console LDAP authentication module configuration, run the command `smreg list -m` on the web console server. The output should mention a module named `com.sun.apoc.authentication.LdapLoginModule` and list its parameters. Check that the server name and port number, as shown in the `ldap.provider.url` parameter are pointing to your LDAP server, that the base DN from the `ldap.baseDN` parameter is the top of your LDAP data tree, and that the LDAP attribute listed in the `ldap.userAttribute` is indeed the attribute used to uniquely identify user entries in the LDAP server.

If anonymous access is disabled, the user DN provided must be the full DN of an entry in the LDAP server which has enough permissions to do read and search operations. It doesn't need to be able to perform write operations, and as such, using here the full DN of an administrator entry is overkill.

+<<Anchor(SetLockhartJava)>>

 ==== Setting the Web Console Java Environment ====

 

 The current Web Console Java environment can be checked by running `smreg list -p` and looking at the `java.home` property. This property must point to a valid Java home, and furthermore that Java home must be a JDK and not just a JRE. If this value is incorrectly set, it can be modified by running `smreg add -p java.home=<JAVA_HOME>`, with <JAVA_HOME> pointing to a valid installation, i.e where the executables `javac` can be found in the {{{bin/}}} subdirectory.

+<<Anchor(InstallAPOCMgr)>>

 ==== Installing APOC Manager ====

 

 To check if the APOC Manager is installed in the Web Console, run `smreg list -a`. One of the registered applications must be com.sun.apoc.manager_<version>. If such is not the case, follow the instructions in the installation guide to install the module.

 ==== Configuring the APOC Manager ====

 

-To check if the APOC Manager is pointing to the proper LDAP server, check the contents of the file named `policymgr.cfg` located in  `/usr/share/webconsole/apoc/WEB-INF`. That file should contain the host name, port number and base DN of the LDAP repository. If the data in that file is not correct, use the `configure` script as described in the second half of the section on [#ConfigureLockhart configuring the Web Console] to provide the proper values. Checking the values are correct can be done by trying to [#FindUser find a user] in the directory using these parameters.

 ==== Enabling Debug Log Level for the APOC Manager ====

 

 The current log level of the APOC Manager, which is actually the log level of the Web Console, can be checked by running `smreg list -p` and looking at the {{{debug.trace.level}}} property. To force the APOC Manager to generate more traces so that the source of problems can be investigated, this property must be changed by running `smreg add -p debug.trace.level=<log level>`, where <log level> is 3 for the maximum amount of traces.

 ==== Enabling Debug Log Level for the APOC Agent ====

 

 To get the APOC agent to generate as many traces as possible to facilitate the investigation of problems, its log level must be changed to the value `FINEST`. This can be done editing the file named `apocd.properties` located in `/etc/apoc`, if a line containing `LogLevel` exists in that file, replace that line with the exact string `LogLevel=FINEST` or if no such line exists, just add the string at the end of the file. Force the agent to reload its configuration by running the command `/usr/lib/apoc/apocd reload`.

 ==== Managing Change Detection in the APOC Agent ====

 

-By default, the APOC agent checks for changes to the configuration of currently logged in users every hour. It can be forced to perform a change detection by running `/usr/lib/apoc/apocd change-detect`. To modify the change detection frequency use the [#ConfigureAPOCAgent agent configuration tool]. Another way is to edit the file `apocd.properties`, located in `/etc/apoc` and, if a line containing `ChangeDetectionInterval` ('''not''' `DaemonChangeDetectionInterval`) exists, replace it with the string `ChangeDetectionInterval=<period>`, where `<period>` is the number of minutes between detection cycles, or if no such line exists, just add the string at the end of the file. Force the agent to reload its configuration by running the command `/usr/lib/apoc/apocd reload`.

 ==== Enabling APOC in GConf ====

 

 To check whether APOC is enabled in GConf, verify that the file `path` located in `/etc/gconf/2` contains lines like `apoc:readonly:mandatory@` and `apoc:readonly` and that these lines are not commented out. The fact that a proper session with the APOC agent has been established when a GConf daemon has started can be tested on Linux by looking in the file `messages` located in `/var/log` and looking for {{{gconfd}}} messages associated with the user.

 === Desktop User Preferences ===

 

 If a user has explicitly chosen preferences for the desktop applications, usually by going to the Preferences menu, these preferences will be used by the application instead of the central values set in the APOC Manager. To force a central value to be used, i.e to prevent users from modifying it, the value must be protected. Refer to the administration guide to learn how to protect a value.
