Shouldn't that be ldap://HOSTNAME:PORT/o=slb,c=blah...

You can see that at first something in his config had a servername
that appeared to be a valid hostname, but then after parsing the URL
to extract the host/port, it was not specified so it resulted in
nothing.
The bus error...isn't that due to free'ing a constant string?
...Todd
The configuration file defines ldap_default_servers:
ldap_default_servers = "\
gb0135ldap00.ldap.slb.com::390"
so the URL correctly substitutes this, and expands, but then after ldap_url_parse one sees the wrong host and port
LDAP parameters: user=NULL pass=NULL size=0 time=0 connect=0 dereference=0 referrals=on
perform_ldap_search: ldapm URL = "ldap:///o=slb,c=an?alias,mail,cn,ou,telephonenumber,o?sub?(&(mail=*)(alias=pkaturi))" server=gb0135ldap00.ldap.slb.com port=390 sizelimit=0 timelimit=0 tcplimit=0
after ldap_url_parse: host=o=slb,c=an port=954024
Hard coding the hostname into the LDAP URL, one gets a slightly different response (no bus error, but still an error in the LDAP URL parsing):

The Solaris version was compiled from source using Exim 4.80.1, while the Ubuntu package was installed as a package, and is based on 4.76. I do not see anything explicitly mentioned for LDAP lookups in the exim 4.80 change logs, but there has been changes to the lookups (new type dbmjz)
