Hello, all:

I'm using IPA 3.0.0-26 on CentOS 6.4:

ipa-server-3.0.0-26.el6_4.4.x86_64
ipa-client-3.0.0-26.el6_4.4.x86_64
ipa-server-selinux-3.0.0-26.el6_4.4.x86_64

kernel: 2.6.32-358.18.1.el6.x86_64

My current setup has four masters replicating to each other and I seem to have 
run into a problem with ldapwhoami on my clients.


$ ldapwhoami
SASL/GSSAPI authentication started
SASL username: testu...@example.com
SASL SSF: 56
SASL data security layer installed.
ldap_parse_result: Protocol error (2)
    additional info: unsupported extended operation
Result: Protocol error (2)
Additional info: unsupported extended operation


The slapd log on one of my masters shows:

[15/May/2014:10:22:01 -0400] conn=35293 fd=95 slot=95 connection from

This is a partial debug from the ldapwhoami command:

Any help you can offer to guide me in fixing this problem would be appreciated. 
Thank you for your time!
