I have built and upgraded one of my openldap servers from 2.4.26 to 2.4.28 (on RHEL release 5.7 x86_64) and with the identical configuration to my other servers, I am seeing the following messages in the slapd.log file:
slapd[4434]: conn=115331 fd=263 ACCEPT from IP=X.X.X.X:51856 (IP=0.0.0.0:389) slapd[4434]: conn=115331 op=0 do_extended: protocol version (2) too low slapd[4434]: conn=115331 op=0 DISCONNECT tag=120 err=2 text=requires LDAPv3 slapd[4434]: conn=115331 fd=263 closed (operations error)
I'm not seeing anything leaping out at me from the change log for 2.4.27/2.4.28 that indicates what I have gotten wrong that worked until now.
As I said, I am running the same slapd.conf file on my 2.4.26 installations and not seeing these failures there at all (and since I use an F5 load balancer, these connections are sprayed all across my pool of servers).
Where should I start looking?
Thanks,
