I have just upgraded my dev Splunk instance to the latest release (4.3.1, build 119532) and realized that my saved searches are no longer able to run successfully. After much checking, I have come to the conclusion that spaces in my username are causing the saved searches to fail. This is not the case for my other Splunk server running a lower version (4.2.3 build 105575).
Regarding the user accounts, they were added through LDAP integration.
Has anyone experienced this before? If so, how were you able to fix it?
Bug SPL-50513 has been filed to address this issue and i appears to be related to bug SPL-21227.
