I configured openldap (port636) with SASL configuration in Centos7.

However getting the following error:

[root@LBNILINUX02 ~]# ldapsearch -v ldap_initialize( <DEFAULT> ) SASL/GSSAPI authentication started ldap_sasl_interactive_bind_s: Local error (-2) additional info: SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available) [root@LBNILINUX02 ~]#

kadmin.local cmd shows the correct output. [root@LBNILINUX02 ~]# kadmin.local Authenticating as principal root/admin@TEST.COM with password. kadmin.local: listprincs K/M@TEST.COM Manager@TEST.COM host/ kadmin/admin@TEST.COM kadmin/changepw@TEST.COM kadmin/ kiprop/ krbtgt/TEST.COM@TEST.COM ldap/ ldap1@TEST.COM kadmin.local:

Please help me if anyone has any idea on this.

Port 636 is, by DEFAULT, the port for SSL connections in LDAP. Again, the openLDAP documentation is ample on how to configure openLDAP with SASL:
