Re: Long ldap session when ldap server failover

Hi Quanah,

It is ssh authentication of a ldap user when ldap server failover. Around that period there was about 6-8 concurrent ldap sessions from the same client.
Top command showed no process was hungry.

Could any reason made it delay so much? Could any special message from ldap server make client wait?

Well, it shows that the LDAP client didn't unbind until after 5 minutes.
We have no idea *what* that client is, only you do.  What is
"cn=ProxyUser,ou=proxyagent,ou=com,dc=jerarm,dc=roma,dc=te,dc=com"? Are you
sure it's an *openldap* client or is it something else?
