The timestamps from the logs are missing, so it's not clear which call
is taking long. No server lookups should be performed in the account
phase, though, so I can only think of the selinux label setting in
libselinux, which is also done in the account phase to be taking long.

can you try to disable the selinux provider for a test?
    selinux_provider=none
btw why is the 'fast' client not running the account phase at all? Is
pam_sss in the account stack in the PAM configuration? Is the
access_provider set to anything else than IPA in the sssd.conf file?
