[Freeipa-users] Deny bind for external LDAP if password is expired

[Prashant Bapat]

In our FreeIPA deployment the clients use pam_nss_ldapd with the "compat"
schema. No ipa-client.

I'm planning to apply the patched ipa_pwd_extop plugin to only 2 of the
replicas (out of 8) where the external app authenticates against IPA's
LDAP. These 2 replicas are more used like readonly. The Web UI where the
users login and change their profile is not on these replicas.

With this LDAP binds are denied to users with expired passwords from the
external app.

Will this setup have any issues, related to replication etc ?
