[keycloak-user] ldaps configuration --> Bug or regression with ldap connection ulr

[Marek Posolda]

Hi Meissa,

I don't think that we changed anything in this part related to ldaps, 
truststore SPI etc, but I could be wrong. We upgraded Wildfly, but this 
doesn't look that it is related to Wildfly upgrade (although again not 
100% sure TBH).

Also this could be a bug in Java. Are you using same Java version you 
used with Keycloak 3.4.3.Final?

Another question is, how problematic it is to change "LDAPS://" to 
"ldap://" in the configuration? Any issues with changing that in your 
environment?
