Re: Error while updating olcDbConfig

[Daniel Jung <mimianddaniel@gmail.com>]

following seems to indicate that it isn't a permission issue. I am 
running old version DB, 4.7 from our favourite distro repo :(
Seems like there is transaction that is not being closed properly??

<= ldap_bv2dn(cn=Manager,cn=config)=0
=> ldap_dn2bv(272)
<= ldap_dn2bv(cn=Manager,cn=config)=0
=> ldap_dn2bv(272)
<= ldap_dn2bv(cn=manager,cn=config)=0
