#1

This error fires up regularly in my xwiki log:

2018-12-14 12:29:19,407 [http://127.0.0.1:8080/bin/loginsubmit/XWiki/XWikiLogin] ERROR o.x.c.l.XWikiLDAPConfig        - Error parsing LDAP fields mapping attribute from configuration, got [=]

What can I do to fix this ?

This error suggest that you have something wrong in the property xwiki.authentication.ldap.fields_mapping in xwiki.cfg file or its wiki side equivalent (it’s supposed to contain a list of key=value and looks like one of that list element is just =).

#3

I can not see the bug may be you see it:
xwiki.authentication.ldap.fields_mapping=last_name=sn,first_name=givenName,email=email

I have no settings in the LDAP GUI may cause this the problem ?

#4

Looks OK to me.

You never modified it or you are not using it anymore ?

#5

I migrated this from 8.3 I can not say for sure that the GUI was not used earlier. Now there are no setting. Just two empty field pairs.
