It seems the following set-based constraints falsely fail even with valid
modifications:
---------------------------- snip ----------------------------
# cn value has to be concatenated givenName SP sn
constraint_attribute cn,sn,givenName set
"(this/givenName + [ ] + this/sn) & this/cn"
restrict="ldap:///ou=People,dc=infraldap,dc=onlinebrief,dc=de??sub?(objectClass=dpagE2Person)"
# homeDirectory value has to be concatenated "/home/" uid
constraint_attribute uid,homeDirectory set
"([/home/] + this/uid) & this/homeDirectory"
restrict="ldap:///ou=People,dc=infraldap,dc=onlinebrief,dc=de??sub?(objectClass=posixAccount)"
---------------------------- snip ----------------------------
When I disable both valid modifications work.
Ciao, Michael.
