  • 1.  ISAM Error: HPDIA0114E Could not acquire a client credential.

    Posted Fri December 06, 2019 11:38 AM
    Hello,

    we have recently migrated from Oracle LDAP to Microsoft LDS. On the part of change I have configured the LDS configuration on ISAM runtime environment. everything looks fine but getting below error when user try to login to application pages. Here surprising thing is whenever user tries to login second time its user can login but some times getting below error.
    ISAM Error: HPDIA0114E Could not acquire a client credential.

    We have ISAM Internal and DMZ appliances . Please suggest me if there is any configuration needed in order to overcome the above error.

    Thanks,
    Venugopal.

    Please refer https://www.ibm.com/support/pages/error-text-cant-contact-ldap-server

    With "connection-inactivity = 0", each connection from webseal to LDAP is persistent... upon startup, webseal opens some small number of connections to LDAP... with higher loads, webseal opens up to a maximum of 16 connections... as load goes back down, webseal would only be using a subset of the existing connections to process requests... ANY of the unused connections then run the risk of exceeding the external inactivity timeout set at either firewalls, LBs, and or LDAP itself... and if webseal then gets to the point of trying to use one of those stale connections, you will get the failed to contact LDAP server messages...

    Hi Venugopal,

    try to telnet from ISAM to LDAP on the LDAP listening port using the following command tools connect IP:Port and see if the connection is successful, if not it maybe connection issue or the LDAP service is down.

    Hello,

    We are not seeing this error every time. But it will be happened after user is inactive for some time and when user tries to login again after 180 seconds  then we will see this issue.

    Thanks,
    Venugopal.

    Hi,

    I too observed the same and most of the time reason is "network" issue b/t webseal and its LDAP. Please check in respective trace logs (runtime trace ) and you would be able to see the connection issues messages logged.

    Secondly: You can have packet trace on and keep the max number of files limit to avoid disk space issues and performance.

    If you can manager, check thee connectivity soon after the issue is reported. Its difficult to telnet the time issue but would help if you can manage it.


    Thanks,
    Rahil
