Hi,

 

This seems to be a message on the LDAP server itself, so it's a bit hard of thinking why the F5 would be at fault for this. Is the F5 setup for LDAP or LDAPS? See: http://social.technet.microsoft.com/wiki/contents/articles/2980.ldap-over-ssl-ldaps-certificate.aspx

 

Is this message logged when traffic is passing to the LDAP or is it caused by monitors?

 

I would advise you to try and verify what's communicated between the F5 and the server (packet captures) and see if you notice anything strange (SSL version mismatch?).

 

If you can't figure it out, you can always open up a case with Support and they can help you. Please see what relevant data you should include: http://support.f5.com/kb/en-us/solutions/public/2000/600/sol2633.html?sr=38220646

 

Cheers!
