Monitoring Client Status

This section shows various commands that can be used to help determine the state of the LDAP client environment. For more information see the section on troubleshooting which will give more information on common problems and how to solve them. Also see the man pages for additional information on the options that can be used.

Verifying ldap_cachemgr is running

The ldap_cachemgr daemon must be running and functioning correctly at all times. Otherwise, nothing works. There are two ways to check if ldap_cachemgr is running.

• Use ps -ef.

  # ps -ef | grep ldap_cachemgr

• Pass the -g option to ldap_cachemgr.

  This causes it to dump the following status information, which is useful when you must diagnose a problem.

  # /usr/lib/ldap/ldap_cachemgr -g

  cachemgr configuration: server debug level 0 server log file "/var/ldap/cachemgr.log" number of calls to ldapcachemgr 19 cachemgr cache data statistics: Configuration refresh information: Previous refresh time: 2001/11/16 18:33:28 Next refresh time: 2001/11/16 18:43:28 Server information: Previous refresh time: 2001/11/16 18:33:28 Next refresh time: 2001/11/16 18:36:08 server: 192.168.0.0, status: UP server: 192.168.0.1, status: ERROR error message: Can't connect to the LDAP server Cache data information: Maximum cache entries: 256 Number of cache entries: 2

Checking the Current Profile Information

Become superuser and run ldapclient with the list option.

# ldapclient list

NS_LDAP_BINDDN= cn=proxyagent,ou=profile,dc=west,dc=example,dc=com

Currently the /var/ldap files are in ASCII format, but that could change to binary at some time and cating the files would cause problems. ldapclient list is the supported method for accessing this information.

Verifying Basic Client/Server Communication

The best way to show that your client is talking to the LDAP server is with the ldaplist command. The simplest form, ldaplist with no arguments will dump all the containers on the server. This works as long as the containers exist, and do not have to be populated. If the first step works, you can try ldaplist passwd username or ldaplist hosts hostname but if they contain lots of data you might want to pick a less populated service, or pipe them to head or more.

Checking Server Data From a Non-client Machine

Most of the commands above assume you are already an LDAP client. If you have not created a client and want to check the data on the server, use the ldapsearch command. The following example lists all of the containers.

# ldapsearch -h server1 -b "dc=west,dc=example,dc=com" -s one "objectclass=*"
