SSH - 1s hang at "Entering interactive session" (Not DNS; possibly SELinux related)
Solution 1:
This may not be related, but selinux related slowness has been report for IPA-based accounts here: https://access.redhat.com/discussions/3499951
The solution for that case is:
I looked into SSSD and IPA user forums and since my systems do not use SELINUX, I went ahead and added this to the domain section in the sssd configuration:
selinux_provider=noneAfter this the login process is immediate, as expected.
