Hi, there is some problem with setting up ldap replication. I have folowed instructions to configure replication (replica pw, master url etc.) but when I try to check replication by "zmprov -l gaa" on slave server I get many errors with TLS:

Code:
zmprov -l gaa
[] FATAL: failed to initialize LDAP client
com.zimbra.cs.ldap.LdapException: LDAP error: : The connection reader was unable to successfully complete TLS negotiation:  javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: d2:CN10:zcs.example.ru1:O12:TEST Software2:OU27:Zimbra Collaboration Server6:accept4:true5:alias21:zcs.example.ru:13591175054:fromi1359117508000e4:host10:zcs.example.ru3:icn10:zcs.example.ru2:io27:Zimbra Collaboration Server3:iou27:Zimbra Collaboration Server3:md532:D58363D449AE59A5256573A88FA457958:mismatch5:false1:s10:13591175054:sha140:8A04D407FFE18D4E681FC44B06FF79B1E920C8F12:toi1422189508000ee caused by java.security.cert.CertificateException: d2:CN10:zcs.example.ru1:O12:TEST Software2:OU27:Zimbra Collaboration Server6:accept4:true5:alias21:zcs.example.ru:13591175054:fromi1359117508000e4:host10:zcs.example.ru3:icn10:zcs.example.ru2:io27:Zimbra Collaboration Server3:iou27:Zimbra Collaboration Server3:md532:D58363D449AE59A5256573A88FA457958:mismatch5:false1:s10:13591175054:sha140:8A04D407FFE18D4E681FC44B06FF79B1E920C8F12:toi1422189508000ee
