Issue:

We run Identity Manager integrated with CA Single Sign-On, and when the users have to change their password, the IdM server reports error : 

"Corrupted buffer returned from server" 

We can see that the Policy Server cannot contact the Provisioning server myhost.mydomain.com : 20000. The Policy Server reports LDAP error 81.

How can we solve this ?

 

Environment:
Policy Server 12.51CR00 on RedHat 6; User Store is CA Directory;
Cause:

LDAP User Store certificate was wrongly encrypted, and it has been recently changed, which was causing this issue.

Resolution:

Sign again the original certificate, and set both the certificate and its CA certificate in both the LDAP User Store certificate store, and the Policy Server certificate store to solve the issue.
