Full_Name: Quanah Gibson-Mount Version: 2.4.46 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (47.208.148.239) As noted in the OpenLDAP source (http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=blob;f=servers/...) there is an issue with controls being reset with a new extended operation. This is problematic for a proxy auth mechanism being developed, as it needs to have the controls preserved while passing an extended op to slapd. A possibility would be to re-register the control, adding the corresponding extended operations, but the parsing function resets them so this unfortunately is not an option.
