When running Strategy Secure Enterprise 10.x or 2019 on Linux and using LDAP for authentication the Intelligence Server process may shutdown unexpectedly.
The issue is caused when using libldap libraries as the LDAP connectivity library. Starting with Strategy Secure Enterprise 10.x, LDAP authentication is now handled in a way that takes advantage of multithreaded architectures. The issue occurs because the underlying libldap libraries are not thread safe and thus it's possible an exception within them will cause the Strategy Intelligence Server to crash.
When implementing LDAP authentication in Strategy Secure Enterprise 10.x or 2019 and above, users should use libldap_r as the LDAP connectivity libraries as this should be thread safe as shown below:
This library is included as part of the standard OpenLDAP package available via RHN.
In addition to switching the connectivity library as outlined above, it is also recommended users upgrade the version of OpenLDAP package on their system to the latest available. It's been seen some older versions of the package can still experience stability issues even when using the libldap_r connecitivity library.
If none of the above actions resolve the error, see KB424161.
The Strategy internal reference number for the issue discussed in this document is DE28486.
