ldapsearch by uid and mailAlternateAddress - is this indexing problem?

[Petri Laakso <petri.laakso@pp.htv.fi>]

Hello,

I've have a problem with slapd/ldapsearch.

First time I try to search only with uid as filter which 
did not return any results, but then with the second search,
mailAlternateAddress as filter i've get expected response
Could this be cause of corrupted uid index?


Searches and their results:

** With uid as filter **

# extended LDIF
#
# LDAPv3
# base <ou=People,dc=foo,dc=bar> with scope one
# filter: (uid=someuid)
# requesting: ALL
#

# search result
search: 2
result: 0 Success

** Next, search with mailAlternateAddress as filter **

# extended LDIF
#
# LDAPv3
# base <ou=People,dc=foo,dc=bar> with scope one
# filter: (mailAlternateAddress=john.doe@foobar.net)
# requesting: ALL
#

# someuid, People, foo.bar
dn: uid=someuid,ou=People,dc=foo,dc=bar
uid: someuid
sn: Doe
cn: John
uidNumber: 123456
gidNumber: 12345
mailAlternateAddress: john.doe@foobar.net
... etc ...

# search result
search: 2
result: 0 Success

# numResponses: 2
# numEntries: 1
