Cannot Flow Null Multi-Valued Attributes to Connected Directory (281622)
The information in this article applies to:
- Microsoft Metadirectory Services 2.2
- Microsoft Metadirectory Services 2.2 SP1
This article was previously published under Q281622 SYMPTOMS
The Management Agent may not flow a null multi-valued attribute out to the connected directory. If the attribute is a single-valued attribute, the null value successfully flows out to the connected directory. This problem is seen when a multi-valued attribute in MMS is deleted so that the value is null.
CAUSE
The output templates uses the $multivalued function to correctly format the text in the outgoing (create) file, for example:
($multi_valued("0",$userCertificate;base64,"-userCertificate;base64: "))
The function requires a value to process and will not work with a null value.
RESOLUTION
To work around this problem:
- Remove the existing simple or advanced attribute flow rules for this attribute.
- Type the following into the advanced attribute flow script, replacing userCertificate with the name of the target attribute:Advanced flowscript Modification:
replace
$cd.userCertificate = $mv.userCertificate
with:
IF $EXIST($cd.userCertificate) = T
###########################################################
# the attribute existed in the connected directory the last
# time that we ran a discovery
###########################################################
THEN
IF $EXIST($mv.userCertificate) = F
#################################################
# the metaverse value has been cleared so send a
# NULL to the connected directory
#################################################
THEN
###################################################
# even though this attribute does not appear in the
# output template, a "cd" assignment *must* be made
# to force the creation of the create file
###################################################
$v_userCertificate=-userCertificate:
$cd.userCertificate = $null
ELSE
$cd.userCertificate = $mv.userCertificate
ENDIF
ELSE
##################################################
# the connected directory did *not* have the
# attribute the last time that we ran a discovery
##################################################
$cd.userCertificate = $mv.userCertificate
ENDIF
- Modify the EXPORT template Add/Mod with:
($multi_valued("0",$userCertificate;base64,"-userCertificate;base64: "))
($v_userCertificate)
