LDAPS VIP not working

Hi all,

 

Recently after upgrading our f5 vcmp guest from 11.2.1 to 11.4.1 HF3, the ldap virtual server stopped working.

 

Although the VS is showing as UP & traffic flow is shown as fine, Application teams got the error of "LDAPS Handshake not completed" in their error logs.

 

After we rolled back to 11.2.1, it started working again.

 

Has any one faced this type of issue earlier in 11.4.1..? Is it a kind of bug.? Or working difference in 11.4.1..?

 

Regards Narendra
