The term "uid" is kind of overloaded here. We're looking for non-unique
UID numbers, not the uid LDAP attributes, which store the name.
Something like this might show the offender:
ldapsearch -LL -x -D 'cn=Directory Manager' -W -b
'dc=sri,dc=utoronto,dc=ca' '(uidNumber=54184)'
Thanks Jakub, there
is a conflict uidNumber indeed.
What I tried was "getent passwd 54184", it gave me just one entry which got me
to believe
that it is unique...
Thank you all for your time and wisdom.
