Event Tracing for LDAP Applications - Essay Example

Number A number of methods can be used to check for LADP problems. Various commands may be used to assistin determining LDAP client environment. This paper looks at methods of LDAP problem detection as well as its troubleshooting tools.Verifying if Idap-cachemgr RunsFast of all, the Idap cachemgr daemon has to be running as well as correctly functioning all the time. If not, then nothing is working. Two ways could be used to check ifthe Idap-cachemgr runs (IBM, 2012).use ps-ef#ps-ef I grep Idap-cachemgrPass the –g option to Idap-cachemgr –gThis makes it dump some status information that becomes useful where the problem has to be diagnosed.

# /usr/lib/Idap-cachemgr-gChecking current Profile InformationGet to be a super user then run Idapclient by means of the list information.Idap list“NS_LDAP_FILE_VERSION= 2.0NS_LDAP_BINDDN= cn=proxyagent,ou=profile,dc=west,dc=example,dc=comNS_LDAP_BINDPASSWD= {NS1}4a3788e8c053424fNS_LDAP_SERVERS= 192.168.0.0, 192.168.0.1NS_LDAP_SEARCH_BASEDN= dc=west,dc=example,dc=comNS_LDAP_AUTH= simpleNS_LDAP_SEARCH_REF= TRUENS_LDAP_SEARCH_SCOPE= oneNS_LDAP_SEARCH_TIME= 30NS_LDAP_SERVER_PREF= 192.168.0.0NS_LDAP_PROFILE= pit1NS_LDAP_CREDENTIAL_LEVEL= proxyNS_LDAP_SERVICE_SEARCH_DESC= passwd:ou=people,?

The supported way of eccessing such information is the Idapclient list.Verification of Basic Client/ Server CommunicationBy means of the Idaplist command is the best method to show that a client is communicating with the LDAP server. The simplest form, Idaplist will without arguments dump every container on the server.

So long as these containers exist, then this will work. On condition that step 1 works, one may attempt Idaplist password username, or even Idaplist hosts hostname, however, in a case where they consist of immense data then one has to pick a service that is lesser populated, or even pipe them to head or more (IBM, 2012). Problem configuration and solutionsUnresolved Host NameSolaris operating environment LDAP client back end does return hostnames that are fully qualified for host lookups, for instance hostnames that have been returned by getipnodebyname(3N) as well as gethoatbyname (3N).

in a case where the stored name happens to be qualified and containing one dot, the name will be returned by the client as is. For instance, if hostB.eng is the stored name, hostA.domainname is the return name.In a case where the name stored within the LDAP directory happens to be unqualified (contains no dot) the client back end then appends the domain part to the name. For instance, if hostA is the stored name, hostA.domainname is the return name. Inability to Reach Systems within LDAP Domain RemotelyIn a case where the name of the DNS domain is not similar to the LDAP domain name, the service of LDAP naming cannot be used in serving host names except where host names get to be stored fully qualified (ORACLE, 2011).

Login is Not WorkingLDAP clients make use ofpam(3) modules for authentication of users during logins. Where using standard UNIXTM PAM Module, password gets to be read from the server as well as checked on client side. The following are some of the reasons why this may fail: 1. Idap fails to be used by password service within the /etc/nsswitch.conf file2. Proxy agent may fail to fail to have the correct password’3. Entry fails to have ahadowaccount object class,4. User has no password defined for him/her5.

No LDAP server that are reachable (ORACLE, 2011)Check server status6. Pan.conf is not correctly configured7. User not defined within LDAP namespace,8. Password not stored in a crypt format, among others (IBM, 2012).Lookup to SlowLDAP database does rely upon indexes for improvement of search performance. Performance degradation will occur where indexes are not configured properly. Common attributes sets are contained within documentation that are need to be indexed. For site performance improvement, one can add other indexes.

Idapclient unable to bind serverPossible reasons for idapclient failure to initialize a client while using int profile option include:1. Domain name that is incorrect spacified in the command line2. Improper setting of the access control information on the server,3. Server address that is not correct passed to idapclient command, among others.Windows Vista as well as windows server 2008 introduces Event Tracing for these applications that make use of LDAP (Lightweight Directory Access Protocol.

Certain areas within LDAP provider do have an underlying implementation, which happens to be complex or includes some sequence of steps which make problems’ diagnosis within such areas more difficult. Event tracing is a quite valuable tool for trouble shooting. ReferencesIBM. (2012). LDAP configuration management and troubleshooting on AIX.
