Description Florian Best

2016-07-13 10:10:45 CEST

When modifying a UDM object which has uppercase characters in its identifying DN attribute name there is always a modrdn operation done with the same DN as before.

# strace python -c "__import__('univention.uldap').uldap.getMachineConnection(0).modify('univentionAppID=samba4_4.3,cn=samba4,cn=apps,cn=univention,dc=school,dc=local', [])" 2>&1 | grep univentionAppID                                                             
write(3, "0s\2\1\2ln\4MuniventionAppID=samba4_"..., 117) = 117

Regression due to svn r70685 / Bug #40041 / UCS 4.1-2 errata 207.
