I guess a plugin startup may delay the DS startup itself and some
pstack during that minute will give us some info.
Regarding the krb authentication this is difficult to say if they are
delayed by the number of users. You may issue something like 'ipa
user-find <xxx>' and the access log should show if the authentication
phase is really slow.
If slapi-nis is active, it populates its tree on startup, delaying
actual start of 389-ds. This is fixed in slapi-nis 0.55 (in Fedora) and
will be available in RHEL 7 in next update.
You can check if it is a culprit by disabling compat tree. However,
currently compat tree is used by SUDO in SSSD.
