SLAPD wont start
 

I am trying to set up LDAP on an FC5 box with the default instalation of openldap. I have configure slapd.conf but when i try to do
# service ldap start it gives me

Checking configuration files for slapd: config file testing succeeded
[ OK ]
Starting slapd: [FAILED]

I dont know what to do next
Pleas help

errr,,, update

when I comment out the TLScertificate lines, and i use
# service ldap start it gives
Checking configuration files for slapd: config file testing succeeded
[ OK ]
Starting slapd: [ OK ]

there is also a line for slapd on ps aux

but when i do
#service ldap status it gives
slapd is stopped


and i dont think the service is listening on the required port (389)
