Under specific circumstances, which seem to be something around: - using IPA under Internet Exploder - machine part of AD (Windows-only network, not part of IPA) - with user entering login/password via Krb5Passwd (not negotiate) - leaving the window untouched for a couple of minutes a JSON error pops up (see screenshot). The server is not under any load, network throughput is fine, and repeating the action eventually leads to the action being executed. /var/log/httpd/error.log gives me these hints: [Thu Jun 14 16:04:57 2012] [error] ipa: ERROR: release_ipa_ccache: ccache_name (FILE:/tmp/krb5cc_apache_q4B5Vw) != KRB5CCNAME environment variable (FILE:/tmp/krb5cc_apach [Thu Jun 14 16:04:58 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: batch: i18n_messages(): SUCCESS [Thu Jun 14 16:04:58 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: batch: user_find(None, whoami=True, all=True): SUCCESS [Thu Jun 14 16:04:58 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: batch: env(None): SUCCESS [Thu Jun 14 16:04:58 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: batch: dns_is_enabled(): SUCCESS [Thu Jun 14 16:04:58 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: batch(({u'params': [[], {}], u'method': u'i18n_messages'}, {u'params': [[], {u'all': True, u'whoami [Thu Jun 14 16:05:00 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: JSONError [Thu Jun 14 16:05:00 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: json_metadata(None, None, object=u'all'): SUCCESS [Thu Jun 14 16:05:06 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: json_metadata(None, None, command=u'all'): SUCCESS [Thu Jun 14 16:05:08 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: user_find(None, sizelimit=0, pkey_only=True): SUCCESS [Thu Jun 14 16:05:09 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: batch: user_show(u'admin', all=True): SUCCESS [Thu Jun 14 16:05:09 2012] [error] ipa: INFO: user_obscured@DOMAIN_OBSCURED: batch: user_show(u'bztest', all=True): SUCCESS etc ....

I still have the logs handy, if you point me to the right direction before they (log)rotate to log heaven, I'll be glad to paste them here. ipa-2.2.0-14.el6

One more thing perhaps related: the action leading up to this is entering part of the name into the search box and hitting enter.

This issue is not reproducible any more with the latest bits. Moving to QE to retest.
