LDAP integration error

[tombo]

Activiti-explorer 5.15 LDAP integration is throwing an error on task review. It's trying to fetch user picture although no user picture attribute is set in the configuration. (tested with Apache DS)

That is indeed true. It's probably better to return null there. For the moment, you can work around it by extending the LDAPUserManager class and overriding that method, and plugging your custom class in similar to the default LDAP configurator.

[tombo]

Confirmed. Returning null on getUserPicture method does the trick. For convenience, modified version is attached.

Your file is not readable. Maybe the wrong charset?

[tombo]

Just rename it to .jar.

Will this issue get fixed in the next activiti Release?

Best regards,
Ben

[b_schnarr]

No answers?

Missed this post somehow. Thanks for the bump.
