LDAPS problem after update from 9.6.3 to 9.7.3

Hello,

after update SMC from 9.6.3 to 9.7.3 LDAPS to Microsoft DC doesn't work anymore.
In server.log I find

... [Root exception is javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)].....

LDAP without SSL is running fine.

Best regards
Michael
