Upstream ticket: https://fedorahosted.org/sssd/ticket/1147 I've been triaging this issue with Kaushik's help. Neither of us was able to reproduce the issue with 1.8, only with 1.5.x. Considering the amount of changes between 1.5 and 1.8, we are closing the ticket as closed in the current release. In case the bug hits us again, here are the symptoms I was seeing with 1.5: I instrumented SSSD code with getsockname() calls to be able to cross-reference the client machine port with logs on the LDAP server. The LDAP server logs indicated that the bind operation completed successfully, but SSSD never called the _done() callback for the operation. After the hardcoded sdap_op timeout passed, the bind operation timed out, marked the whole request with an error and marked the provider as offline. Another suspicious thing was the *after* the request that later timed out was issued, several others were started and completed successfully.
Technical note added. If any revisions are required, please edit the "Technical Notes" field
